Step 5Add water, plug, and shoot.
Add 1/8 teaspoon (about ten drops with eyedropper) of water into the barrel and rotate the whole thing upside down to route the water into the boiler.
Cut out a potato plug using an extra piece of scrap pipe and insert the plug into the barrel. This should have an airtight seal and want to push back out, it should not go far into the barrel.
Wedge the cork into the barrel; don't overdo it.
Move the butane bottle down to open the fuel valve.
Click the piezo clicker to ignite the flame.
Point and wait about 1 to 2 minutes.
POP! The spud should fly; mine has a range of about 25 to 35 feet.
If it takes much more than 2 minutes to pop, then turn off the flame and let it cool off for a while; either the air leaked around the potato and cork or the cork was in too tight.

you should take a peice of pipe and try to extrude the end to make it wider/ flared. use this to cut your potato "corks". without needing an actual cork
