Sorry to be picking on details, but the chemistry teacher in me , can´t
resist it. Acetylene has a tripple bond between the carbons, not a double
bond. The tripple is what makes it so reactive. Each of those bonds are
relatively weak and so prone to break.
As for the O/A explosions, my chimistry teacher in high school did it
with a glass beaker wrapped in a towel. One heck of a bang and the beaker
was just dust.

An acetylene (C2H2) molecule - Each "/", and "\" is a molecular bond,
the "=" is the double-bond. C is a carbon atom, H is a hydrogen atom:
