Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Barrel
The barrel is a 1"1/2 by 5ft PVC pipe with the
Step 2: Combustion Chamber
The combustion chamber is basically a 3" by 3ft piece of PVC pipe with a screw cap on one end and a 3" to 1"1/2 reducer on the other
Step 3: Barrel Front
On the front of the barrel you should shave it down so it looks like this. Without it you could not fit the potato in and by that I mean it carves the potato to the right size.
Step 4: Sparker
The sparker is just a grill igniter
Step 5: Sparky Thing
My dad drilled a hole in the top then I fed the igniter wire through for some resin there was a little metal thing at the end and it could not fit in the combustion chamber so we sawed a part of it off then glued it in
Step 6: Connection
Step 7: Hair Spray
Hair spray is the stuff that explodes to shoot the potato to put it in you have to unscrew the cap on the back of the combustion chamber and spray it in ,DO NOT SPRAY ON SPARKER if you do it could rust
