Kids in Timor love to make and shoot slingshots. As I watch them pull the rubber bands back and set the stone to sailing, I always think of Uncle Isaac Newton’s laws of motion. Here’s a fun little set of experiments we developed for teachers to demonstrate those laws in the context of slingshots.
Gather stuff
Forked branch
Rubber bands, maybe 20
Piece of sturdy cloth
Loop of yarn or a stick to scratch a circle on the ground
Rocks: two the same, one big and one small
Gather tools
Saw
Scissors

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
