The perfect Angry Birds to use in a 3-man slingshot.
It’s 10:00 AM on a Tuesday in July. The “I’m bored” has already happened twice. You could hand over a tablet, but there’s something genuinely satisfying about watching a well-aimed ball demolish a cardboard tower in real life that no touchscreen can match.
This backyard project takes the core idea of Angry Birds and moves it outside into a screen-free summer activity. Part craft, part engineering, and kids tend to stay at it longer than you’d expect.

Why it holds up for summer
The physics of stacking and knocking things down are interesting to kids even when they don’t know they’re learning anything. You’re working with gravity, weight distribution, and basic structural engineering, but it just looks like fun. The whole setup runs mostly on boxes you were going to recycle. You can scale from a knee-high tower for a toddler to a full block party course for a dozen kids.
Phase 1: The scavenger hunt

Spend the morning collecting building materials. Amazon boxes, cereal boxes, and shipping tubes are your best options. If you want to stretch the activity out, have kids paint the boxes to look like wood, stone, and ice before construction starts. It adds an hour of craft time upfront and makes the eventual demolition feel more earned.
Phase 2: Make the characters

Seven-inch playground balls work well as projectiles. Heavy enough to knock over a good stack of boxes, soft enough for backyard safety. For the piggies, green Solo cups or green balloons both work fine. Let the kids draw the faces. They will lean into “ridiculous” on their own.
Phase 3: The launcher

A three-person water balloon launcher is worth getting if you don’t have one. One kid holds each side, one pulls back, and you’ve accidentally created a teamwork exercise. If you’d rather build something permanent, a PVC pipe slingshot with heavy-duty exercise bands is a solid afternoon project for older kids. It requires real tools and holds up through many sessions.

I love angry birds and my family is going to make a party!!!! (Angry Birds theme song)
That sounds like so much fun! Make sure to come back and let us know how it goes!
