I am irresistibly drawn to these things.

I miss my potato guns.

My two favorite were my pneumatic gun that hooked up to an air compressor. Can't believe how far that thing could launch a potato. My other favorite was a modified version of that I hooked up to a scuba tank so it was more portable.

In high school, I built a beer can mortar that used M80s as the powder charge. (Remember, I was also an illegal fireworks dealer, so M80s were available to me cheap and in volume). The galvanized pipe had a bore that handled beer cans perfectly as the shell, you just had to put some sand in them.  I could fire those cans almost out of sight.

But why not?  Looks like a lot of fun, it's cheep and sounds a lot safer than your old m80 beer cannon which sounds like it could have killed you.

I really like that guy's videos btw.

Because I'm never satisfied with just a little mischief.

Well, THAT was cool but it only went 100 yards. I wonder if a full length of 6" pipe could make a howitzer that could fire a frozen chicken at those houses across the river?

>killed

I eventually moved up to pipe bombs. Grossly underestimated how powerful they were.  Rattled windows for at least a quarter mile around. Massive hole.

He does a great job on the 2 I've watched.

I'm liking the sound of a frozen chicken cannon.

If I had a machine shop I would find something with a 1.68 inch bore. That would be the perfect size for a golf ball. Seems like that would be a fun one.

I always wanted to build a bigger cantaloupe or watermelon sized cannon but I am guessing I would have blown myself up trying to launch stuff that heavy.

For a quick and easy bomb I always liked dry ice with a bit of water in a plastic soda bottle. Not quite pipe bomb power but enough to make the neighbors nervous.

>frozen chicken cannon

The chicken gun (also known as the chicken cannon, turkey gun, or rooster booster) has been around since 1972. It's used for the "chicken ingestion test," one of a series of stress tests required by the Federal Aviation Administration before a new jet engine design can be certified.
