I don't believe so, I think it has to do more with seeing something novel that you don't get to see every day. Like, not many people have the means to fill a house with elephant toothpaste, so when someone does that it makes for a pretty entertaining video.

No. What does liquid nitrogen have to do with "real science", and since when do people get shooed away from it?

Those videos are the sciency equivalent of fidget spinners.

I have this shirt.

I just like cool shit. I don't put that much thought into it.

Almost certainly no. This is the gateway for "the algorithm" to start recommending pop science and science communicators, and from there, a seed will sprout for people to get interested in "real science"

A lot of scientists are not great communicators. I am much better over text than I am in person... I never shoo anyone away in person but I also understand that in social settings most people only ask what I do out of courtesy rather than genuine interest.

People enjoy the way certain people share their passion. This is a bit overdone for gaming channels focused on kids e.g. pewdiepie but there's also the dude building a hut with Neolithic tools, or tasting rations, trying new foods, or just reacting to fried rice (uncle roger), gardening, or powerwashing. Nilered shares his passion for chemistry in a way a lot of people enjoy but for better or worse I don't think it is about understanding Nature as much as it is connecting with a fellow human.

PhDs are philosophy degrees because whether on purpose or not theses are filled with the personal philosophy of the writer wrapped in the paper of whatever research.

I've never been shooed away from understanding real science. Who's doing the shooing?

Kids love potions and they often fail to outgrow that fascination
