[Outbackmanyep]

I attempted this today with good results!

I'd like to see how many of you have tried or will try this, great stuff for demonstrations and to get the kids involved!

I was going to make one similar from a web page, but I ended up making one with a DVD and 2 35mm film canisters cut and glued together at technical looking angles. I cut the slit in one of the canister lids.

Works a treat!
