At first must collect it. This can be completed by piping it via a tube, which comes out beneath a bowl of water with an upside down test tube over it. Now subsequent to collecting the gas cork it.

Now get rid of the cork and put in a light splint. If it is hydrogen, then it will burn with a squeaky pop.
