Build a Marshmallow Cannon that shoots a marshmallow around 50ft in the air,
Step 1: Materials
Stuff to make it.
2ft of 1" PVC pipe
1ft of 2" PVC pipe
One 2" cap (For bottom of cannon)
A converter to go from 2" to 1Â½"
Another converter to go from 1Â½" to 1" (They donât sell 2" to 1")
A small can of PVC cement
A small can of PVC primer (Not required, Helps it though)
A bottle of rubbing alcohol
A bag of 1" marshmallows (make sure not jumbo or they wont fit in barrel)
Step 2: Putting It All Together
First cut all the right lengths of the PVC pipe. (1ft or 2" and 2ft of 1")
Next Prime and glue the cap and one end of the 2" PVC pipe.
Connect them and give it a little time to dry. (Like 30 seconds)
Then prime and glue the other end of the 2" PVC pipe and connect it to the primed and glued 2" to 1Â½" converter and let it dry.
Prime and glue the other end of the converter and connect it to the 1Â½" to 1" converter and let it dry.
Then prime and glue the other end of that and connect it to the 2ft, 1" PVC pipe.
Step 3: Finishing
To finish it up you need to drill a hole on the cap and drill some holes so that the marshmallow doesnt drop into the chamber.
Step 4: To Use It.
To use it you take 2 caps full of rubbing alcohol and drop it down the barrel. Then take the marshmallow and jam it down to the screws. I find that the rod from blinds works very well for jamming it down into the barrel because it is long enough. Then shake the chamber a little bit to make the alcohol spread around it. Finally take a lighter (I like to use a candle lighter because it has a long end and you won't get burnt) and put the flame by the hole to ignite it and the marshmallow should go into the air. If it did congratulations!
Be careful not to hurt yourself or others when using!!!!!!
