🦾 E5 Grab & Lift

A kitten is stuck on the Prototype Workshop shed roof and a ball fell down a drain. We need grabbing and lifting tools, fast!

Explorers, Foundation. Engineer Stamp: Claw Captain.

Lessons

1. The lazy-tongs grabber: Squeeze the handles and the arm shoots out! How does it get so long?
2. The lever lifter: Can a tiny push lift a heavy thing? Let’s move the pivot and see.
3. Grab test: Would rubbery fingers grab better than smooth ones?
4. The castle drawbridge: The castle is under attack by a teddy bear army! Raise the drawbridge!
5. Design Day: Rescue from the pit: Squeaky the toy mouse fell down the drain. Only a clever tool can reach him!
6. Showcase: Claw Machine Carnival: Each team runs a stall. Visitors try to rescue prizes with your tool!

Design challenge

Build a tool that rescues a toy from the bottom of a box without your hand going inside.
