    it depends how short. the ideal barrel size would be one that is the same internal volume as the amount of hot, pressurized gas created by the popper, so that just when there is no more pressure behind it, it leaves the barrel.i think that if you actually made the barrel slightly longer, it would have pressure behind it for longer, and go faster. however, it all depends on the volume of gas put out by the popper.

    The finished thing. Took me a while to find the right sized barrel. Shot OK.

    just put a bunch of airsoft bbs into the pen and a wad of paper presto airsoft back up weapon.

    Doesn't it seem like a little too much effort for a 1 use thing? Even though, pretty ingenious and a nice little ballistics toy.

    If it's a spring-loaded popper it can be reused:

    No, not too much because it is One use and after using it you ccan just throw it away. Instead of tube just use straw and instead of BLU-TAC use some cheap play-doh or something. One use, sorta like a derringer :D

    Like massachusetts. At least, they require you to get a special liscence to sell them. So most stores dont =(. But the ice cream man does =D

    DUCT TAPE!!!!!! I think that would work pretty well, need to go buy some poppers though- for scientific purposes, of course.

    You could try plasticine or even clay - essentially something that will seal and hold the parts together. If you were happy to have the launcher perform just one shot you could even use glue.
