Ten years ago, I built this thing for a 4th of July party.

Sorry mate. I'm on the Voyager app and there was a huge delay in notifications.

This was basically three potato cannons mounted in an adjustable mortar formation. You could fire off three before having to reset.

Maybe the device led to a lack of thumbs?

From the looks of it, I guess something like a triple potato cannon, but for filling with confetti or similar instead.

It was basically three spud guns mounted on an adjustable base. It's fun seeing how high they go.
