As a person who has made several of these in AP chemistry for a sample lesson, I can tell you the biggest danger is getting the fluid in your eyes mouth or nose. The explosion is very minimal, it is loud however, and to take off even a finger you need at least a 3 liter bottle with the items in question mixed in the right amounts. Also it take a heck of a lot longer than 30 seconds, creates heat and you WILL know well before it blows up. I wouldn’t worry about this in the least. when you pick up a bottle that is full of something, your probably going to dump it out instead of putting all that weight into your bag anyway.
It is always best to error on the side of caution!
