Have fun with a few $ in plumbing and a bag of carrots.  Nice Science Fair project, illustrating pneumatics.
You should enter this in the Redneck Contest!
Good idea. Thanks. <br> <br>OK, I just tried, but the system lists my instructables that are &quot;eligible&quot; for the contest, and this one is not on the list, so I can't enter it!!! I also have a potato gun that is even more Redneck, but I can't enter that either. I sent a request to the brass. Hopefully, they can help with this. -Lou
