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. https://twitter.com/I_am_Endeavour/status/1340788101283803140 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!

Forget it. This demo has no pedagogical value and raises several, including safety, questions. Not worth the bother!
Regards,

A face shield would be best with glasses. As done, hydrogen is escaping into the air and if the person is not careful, that could be another hazard. I agree with Sammye and Jessica - tongs!!
