The color depends on the thickness. It is based on which wavelengths multiple it is, so will cycle through the wavelengths repeatedly, i.e. through the colors, as the bubble gets thinner.
The liquid is probably flowing out of the bubble onto the ground in a slow controlled way, until the bubble gets too thin and pops.

You can also use color rings to tell how gravity and wind are pulling on bubbles, and adding fluid to them should also cycle through the colors. When you attach them to the dispense you can see liquid flow into the bubble.

    Coke. The bad news you either go broke trying to paying for the new addiction trying to post pone the required depressive state or worse you do find it by what is normally progressive more unethical work (crack whore, drug dealer, enforcer, b2b sales, wall street analysts, CEO, etc).

    What do you mean by flash?

    If you mean like a firework, that's because the droplets of oil/whatever get flung out when the surface tension pops.

    If you mean the color changes, as the bubble expands the amount of oil/film becomes thinner and that changes the color due to changing the density.

    Like how there's a very narrow slice of eye color that has enough pigment density to be green when the pupil dilates, but when constricted there's not enough density due to increased surface area and they look blue.

    (To be clear that is a very narrow slice and nowhere near the amount of people who claim their eyes fully change color)

    The detergent is causing a refringent interference of light. Soap moves in a flat layer in the bubble and this causes different light wavelengths to reflect back, interfere with each other, making different colors.

    Oil film...

    Maybe not motor oil, but almost certainly some kind of fluid from a car that contains oil or an oil like substance.

    Just the most likely explanation, if you wash your car in the driveway and this was the first rain, it could just be soap.

    Tell me you have no idea what mania feels like without telling me. It's not some amazing super power. It sucks. It's destructive. And it's not some "part of the brain" to tap into with limitless energy. Your body has limited energy and mania spends it one way or another, almost always to your own detriment.

    If you want to stay up late and do shit drink some caffeine or go get a cocaine habit and quit treating people's affliction like your new hobby of getting things done with this one weird trick.

    I know you probably don't mean anything by this but I still can't help but say fuck you. Mania sucks and fuck you for treating it like some happy fun time tool to be used so you can clean your room or whatever the fuck.

    Quantum tunneling isn't as mysterious as popular discourse likes to make it sound.

    Quantum tunneling involves barriers to movement. Think an insulator around a wire. Electrons can freely move throughout the bulk of the metal and even just a little bit outside of the metal, but they can't transfer to the atoms in the insulating material. However, if you have an arrangement like two pieces of metal separated by a very small bit of insulator, tunneling can become possible. Classical mechanics would say that any amount of insulator between conductors should be able to completely stop charge transfer between conductors no matter how small. However, the wave function that describes an electron's characteristics isn't just a single point. It is spread out a bit. If the insulating layer is small enough, sometimes the electron wave functions will span through the insulating layer and a small portion of it extends into the next conductor. This means that if we measure the charge state on both pieces of metal, every once in a while, the charge state of one will decrease at the same time that the charge state of the other increases by the value of 1 electron. Lots of factors change how often this happens, such as a strong electric field. So do we know where the electron has gone? Not specifically, but we know the charge states of the two regions and it is otherwise confined. Do we know if it is the same electron? No, electrons are completely indistinguishable, and this is actually a pretty important concept for quantum mechanics. But whether it is the same electron, or if there's some exchange that occurs during the tunneling doesn't really matter. We know that a charge transfer has occurred through a barrier without adding or removing energy.

    Mania comes at a cost (my friend's grandfather was manic depressive). Drugs also boost short term function at the cost of long term effects and a refractory period.

    The experience of mania, from the DSM

    Inflated self-esteem or grandiosity

    Decreased need for sleep (e.g. feels rested after only 3 hrs sleep)

    More talkative than usual, or pressure to keep talking

    Flight of ideas or subjectively racing thoughts

    Distractibilitv (i.e., attention too easily drawn to unimportant or irrelevant external stimuli), as reported or observed

    Increase in goal directed activity (either socially, at work or school, or sexually) or psychomotor agitation (i.e., purposeless non-goal directed activity)

    Excessive involvement in activities with high potential for painful consequences (e.g unrestrained buying sprees, sexual indiscretions. foolish business investments)

    The experience of amphetamine from Wikipedia:

    At therapeutic doses, amphetamine causes emotional and cognitive effects such as euphoria, change in desire for sex, increased wakefulness, and improved cognitive control. It induces physical effects such as improved reaction time, fatigue resistance, decreased appetite, elevated heart rate, and increased muscle strength. Larger doses of amphetamine may impair cognitive function and induce rapid muscle breakdown. Addiction is a serious risk with heavy recreational amphetamine use, but is unlikely to occur from long-term medical use at therapeutic doses. Very high doses can result in psychosis, which rarely occurs at therapeutic doses even during long-term use. Recreational doses are generally much larger than prescribed therapeutic doses and carry a far greater risk of serious side effects.^[sources 3]^

    ^[...]^

    Cognitive performance

    In 2015, a systematic review and a meta-analysis of high quality clinical trials found that, when used at low (therapeutic) doses, amphetamine produces modest yet unambiguous improvements in cognition, including working memory, long-term episodic memory, inhibitory control, and some aspects of attention, in normal healthy adults;^[93][94]^ these cognition-enhancing effects of amphetamine are known to be partially mediated through the indirect activation of both dopamine D1 receptor and α2-adrenergic receptor in the prefrontal cortex.^[26][93]^ A systematic review from 2014 found that low doses of amphetamine also improve memory consolidation, in turn leading to improved recall of information.^[95]^ Therapeutic doses of amphetamine also enhance cortical network efficiency, an effect which mediates improvements in working memory in all individuals.^[26][96]^ Amphetamine and other ADHD stimulants also improve task saliency (motivation to perform a task) and increase arousal (wakefulness), in turn promoting goal-directed behavior.^[26][97][98]^ Stimulants such as amphetamine can improve performance on difficult and boring tasks and are used by some students as a study and test-taking aid.^[26][98][99]^ Based upon studies of self-reported illicit stimulant use, 5–35% of college students use diverted ADHD stimulants, which are primarily used for enhancement of academic performance rather than as recreational drugs.^[100][101][102]^ However, high amphetamine doses that are above the therapeutic range can interfere with working memory and other aspects of cognitive control.^[26][98]^

    Even caffeine

    Caffeine is a central nervous system stimulant that may reduce fatigue and drowsiness.^[11]^ At normal doses, caffeine has variable effects on learning and memory, but it generally improves reaction time, wakefulness, concentration, and motor coordination.^[59][60]^ The amount of caffeine needed to produce these effects varies from person to person, depending on body size and degree of tolerance.^[59]^ The desired effects arise approximately one hour after consumption, and the desired effects of a moderate dose usually subside after about three or four hours.^[7]^

    Caffeine can delay or prevent sleep and improves task performance during sleep deprivation.^[61]^ Shift workers who use caffeine make fewer mistakes that could result from drowsiness.^[62]^

    Caffeine in a dose dependent manner increases alertness in both fatigued and normal individuals.^[63]^

    A systematic review and meta-analysis from 2014 found that concurrent caffeine and L-theanine use has synergistic psychoactive effects that promote alertness, attention, and task switching; these effects are most pronounced during the first hour post-dose.^[13]^

    A 2025 systematic review and meta-analysis found that acute caffeine intake can improve reaction time and accuracy for cognitive tasks. Increased dosages can further improve reaction time but lead to decreases in accuracy after specific intake thresholds are reached.^[28]^

    In habitual users, however, tolerance develops rapidly; the perceived attention and alertness boost after overnight abstinence primarily reverses mild withdrawal deficits (fatigue, reduced concentration) rather than elevating performance above a true non-dependent baseline, consistent with the withdrawal-reversal hypothesis.^[64][65]^

    not normally, maybe from drugs you can, but you will have abnormal withdrawl effects. isnt thats why amphetamines are for and thier pharmalogical deratives. i dont think you can have manic phase with drugs though. because manic phase from bpd, usually comes with severe depression, some people have psychosis, or a co-condition like schizophrenia. i once followed a tuber that had manic and depressive phases, apparently the reason he was barely uploading was his "depression phase" followed by his manic phases, (uploading about his cotent which was very sparingly. after a few years, it was reported in the local news, and through another tuber, he took his own life in his depressive phase. it was mostly about pets/talking,not anything extreme.

    Adderall is a quite effective stimulant with manageable side effects, it is also an amphetamine (dextroamphetamine) similar to methamphetamine. I suppose if you mixed that with phencyclidine (PCP) or lysergic acid (LSD) you could probably reliable induce a manic-like state.

    “From the brain” is basically like saying from this impenetrable black box.

    Medications do not work the same on people with the same conditions. You could have exactly the same depression/anxiety symptoms as another person but have a completely negative reaction to an SSRI that works perfectly for them.

    Some people with ADHD can still get high on certain stimulant meds if they take a high dose, but some (like me) don’t get anything but a headache.

    For most people, drinking alcohol is a slightly euphoric experience that decreases inhibitions and makes them feel relaxed. For others (like me) it does nothing or it makes me anxious.

    Now the physical effects do exist in that latter case; my heartrate and breathing do slow if I drink a lot. But the subjective experience is quite the opposite of what its “supposed” to be.

    If you want to feel physically alert, injecting yourself with epinephrine would likely do the trick. But if you want to feel more “manic” as in lacking impulse control, feeling rapid emotional changes, and feeling alert. You likely need a cocktail of drugs specifically tuned for your brain.

    There is no single part of the brain controlling anything. I mean literally anything. There are lots of areas that are involved with certain actions like the hippocampus with memory and V1 with visual input but there are basically no processes that are comtrolled solely by a specific part of the brain.

    And what makes it even more complex is that every part of the brain is recieving different information from thousands of different neurons scattered across the whole neocortex. Some of these connections seem to follow a general trend, but if you’ve ever seen a rabies tracing experiment you’ll know that basically every part of the brain has at least one or two connections from any other part of the brain regardless of function.

    Your brain is a chaotic mess and what little organization exists might not even be necessary. There are mice called Reeler Mice who lack a specific glycoprotein (reelin) which is responsible for organizing the brain into layers. As such, their neurons are scattered all around rather than forming the neat layers and patches that typical mice have. Guess what is wrong with these mice behaviorally? Nothing. apart from the motor issues caused by an undeveloped cerebellum (part of your brain that coordinates muscle movements) they are basically normal mice. (I should note there is some research on reelin levels and relation to psychiatric disorders, but its not well studied and inconclusive)

    You could have a completely different brain than any other human on earth and still function like a normal human. There are people without a corpus collosum (the largest white matter tract in the brain, connecting both hemispheres) who are asymptomatic even though most people with the condition get seizures. There are parts of your brain that might not exist in others like the massa intermedia; and there are no signs whatsoever until you do a scan.

    It is likely your brain is laid out in a unique way that is unlike any other human. Maybe it can carry out processes and emotions and actions the exact same way someone else’s does, but that does not mean both brains are doing that process in the same way. So it is never guaranteed that a drug or stimulation in a specific area which causes the desired effects on one person will cause the same effect on another.

    And the more complex the desired outcome is (e.g. “mania” rather than just “alertness”) the less general your “solution” will be, meaning it will need to be tailored to each subject more specifically.
