Yes, Easter meets 4th of July to kick butt at airsoft.

Step 1: Materials

You will need:
1.Tape
2.A Bottle Rocket (no stick)
3.Some 6mm Airsoft BB's
4.A Plastic Easter Egg
5.A Screwdriver

Step 2: Poking

Poke a hole in the top of the egg with the screwdriver.
Easy enough?

Step 3: Feed the Rocket Fuse Through the Hole

Yet another easy step.
Do I have to explain myself?
Sorry about the pics.

Step 4: Get It Together

Put some BB's in the Bottom part and put it together, then add some tape around the edge to keep it closed, preferrably duct tape.
Edit: Put more tape around it than in the photo

Step 5: Have Fun!

Not really intended to blow your friends' brains out. Not liable for pissed off neighbors finding BB holes in their windows.
Happy Easter/ 4th of July/ Airsoft day/ Whatever

My Friend made this one in the Photo.
