you could always fill them with a mix of water and flower and fire them creating a gooey mess when they land.

one idea that i have not tried and may work well and may be dangerous is spraying a tennis ball with aerosol deodorant and firing it from a combustion cannon, it would make a nice fireball. but I have no idea how well it would work even if it would work at all.

i wouldn't want to be the one cleaning rotten egg out the inside of a spud gun!

thank you for the replies they have been usefull

We don't have Wal marts in the UK

I can't seem to find them anywhere, bot even in a specialists camping shop.

i could always dismantle a BBQ

i am new to building spud guns and still in the proses of building my first and wonder how the barrel length would effect the distance and accuracy?

thanks Insomniac i have been wondering how you get bux and almost made an new topic.
