Dear Taplers,

We have not done this so far because it is more a chemical reaction
but now some of our younger, less peaceful professors wants to show
the hydrogen-oxygen reaction by filling a ballon and ignite it later,
very much like the large hydrogen ballon shown at the physics monster
show in SLC.

Now I assume it will be alright to buy a flask of hydrogen, then fill
a ballon (of course without smoking at the same time) and later
ignite it with a candle on a long stick. Before actually doing it I
want to ask you guys for comments on the necessary safety measures to
perform this without any harm or damage. I would also like to know
how large the ballon should be blown up. Has somebody ever
experienced an accidental ignition form a discharge of a static
voltage? As we know rubbing a ballon can easily produce a large
potential. I do intend to survive this experiment.

Any comments are most welcome....

Wish you a good weekend
