I’m with Ralph on this one. Without context, it doesn’t make sense.
If context is provided, then tongs, gloves, and taking the reaction to a flame (as D Katz suggests) would be indicated. The person in the clip startles when the hydrogen ignites – the risk of dropping the test tube(s) is not insignificant.

Subject: [DCHAS-L] "Hydrogen pop" demo and PPE
Hi all--I'd appreciate any thoughts on someone wearing just eye protection for this demo. On the one hand, it's a small amount and the test tubes don't have constricted necks. On the other hand, it looks like a glass tube held in bare hands
near the face.

It's been suggested as something to post in C&EN's
"Chemistry in Pictures" collection for New Year's Eve, and I need to decide by tomorrow (Wednesday 12/30) whether to go ahead.
Thanks for your input!
