What Happens When You Let Them Launch Things Across the Kitchen
One makes a light turn on. The other launches marshmallows across the kitchen. These are the ones that get carried to a grandparent's house for a demonstration. A coin battery, some lolly sticks, and twenty minutes.
What Happens When You Give a Kid Some Foil and a Reason to Fail
Two challenges where the testing is better than the building. All you need is foil, straws, and tape. Total cost: almost nothing. Total mess: moderate.
What Happens When You Do Exactly What They Tell You

Three engineering projects from your recycling bin: a balloon-powered car, straw rockets, and a rubber band walker. No kit, no cost, no instructions to follow. Just cardboard, tape, and the particular satisfaction of making something work from scratch.
