How to make hydrogen bubbles you can burn in your hand
How to use a hydrogen gas generator to produce explosive bubbles!
Hydrogen bubbles are produced by the single replacement (displacement) reaction between zinc metal and hydrochloric acid. The bubbles can be used in several ways to demonstrate the combustion of hydrogen in the presence of oxygen.
They can be exploded in the hand (as long as your hand is wet!), on the surface of the beaker, or by releasing them and letting them float upwards into an ignition source.

I use safety goggles, and perform in a room with very high ceilings or outdoors. Working with someone with proper training is required when using acids and fire :)

Looks like, I am in front of a chemistry Fire eater Well sir if we try with aluminium instead of zinc would the same happen ?🤔 What did you prefer in this reaction concentrated or dilute H2SO4

Yes, aluminium would work too! You can use some balls of aluminium foil. As for the acid concentration, between 3 and 6 mol/L is the sweet spot.
Fun fact this guy works at my school lol 🤫🤫 no tellem

@@rmahaffy well sir I request one copper sulphide + HNO3 Also Please tell how to distinguish NO2 and Br2 if kept unknown to us and we require to identify them (NO2 and Br2 have same reddish brown colour)!
Don't we need to put on gloves in our hands? Otherwise it's more likely to get burns....

Good question! As long as your hands are very wet (and you are working away from flammable clothing etc), it is quite safe to ignite a small amount of bubbles on your hand. :)
Use gloves pls :)
