I found the picture on Pinterest from 4hbakerco.blogspot.com but there were no instructions so I just winged it. Here’s what I did:
You will need
8 popsicle sticks
1 bottle cap
pom-poms to catapult across the living room or at your older brother
The Dollar Store has a bag of popsicle sticks for $1 so buy in bulk. If you have kids, you need popsicle sticks. The elastics I used are the “ouchless” hair elastics for my daughter, again buy in bulk. They’re $4 for 100, roughly.
Assemble 6 popsicle sticks together with an elastic on one end (or both ends if you prefer but I didn’t find it necessary).
Make a “T” with the remaining 2 sticks, one under the bundle, one over.
Attach with 2 elastics.
Pinch the end shut with another elastic.
Glue a bottle cap to the top, leaving a little stick sticking out to flick with your finger as indicated by the arrows in the first picture.
