This instructable will tell you how to make an Air-Soft grenade thingy.

Step 1: Supplies

These are the supplies you need to make this grenade.

Party Popper
Plastic BB's
Bic Pen
Flat Head Screw Driver
Highly Maneuverable Gloves

Step 2: Taking Apart the Popper

Insert the flat headed screw driver into the edge of the popper and pop out the cardboard cap and keep it for later.

Step 3: Removing the Confetti

This is where you might want to where gloves to protect your hands, I didn't because I'm a bad example. Carefully use the pen to remove the confetti and leave the white cardboard alone.

Step 4: Filling the Popper

Now take your BB's and pour about 20 into the empty popper and replace the cap.

Step 5: Making Sure the Cap Is On

Take the back of your pen and press evenly around the edges of the cap to secure it into place. Then aim and shoot, and it scatters the BB's every where.
