I've lit mixtures of H2 and O2 from electrolysis, and the reaction did
not seem nearly as energetic as acetylene and oxygen.


Acetylene has a free gas molecular weight of about 26. Hydrogen, 2.
Oxygen, 32.

67.2L of gas at 2(H2)+1(O2) ratio weighs 34 grams (3 mole volume)
67.2L of gas at 2(C2H2)+10(O2) ratio weighs 93 grams (3 mole volume)


Sooo... The trash bag full of acetylene/O2 has almost 3 times the mass of
the H2/O2 mixture.

Consider what the relative explosive force of three sticks of dynamite
would be vs. one.
