This is a pea shooter we made as kids. Eye protection recommended if used in battle.
Step 1: Materials
1) Orange or any citrus with a thick peel.
2) "Crystal" Bic Pen
Step 2: Ammo
Peel the Orange
Step 3: Eat the Orange
No use wasting good food.
Step 4: Disassemble the Pen
The plug on the bottom doesn't pop out like the use to, it was rather tricky getting it out. You need to keep the end intact
Step 5: Create the Air Chamber
Press the tube into the peel so a piece of the peel is stuffed tight into the end.
Step 6: Setting the Plunge Trigger
With the ink cartridge push the peel to the narrow end of the tube.
Step 7: Load the Ammo
Repeat step 5 and leave the second piece of peel at the end
Step 8: Ready to Launch
Now cover the tiny hole on the side of the pen tube with your finger so that you will create an air chamber.
Step 9: Shoot
Next use the ink cartidge and and insert it back into the tube at the narrow end. Push it really quickly and the peel on the end should "pop" out and fly 10-20 feet. Push the plunger peel back into position to repeat.
