I wanted to make a catapault from The Dangerous Book For Boys that I got for my birthday, so I asked Mama if I could and she said, "Yes". I drew a plan, which I followed. Here's the end result:
I used chopsticks (which I got told off about), a bottle lid and copious quantities of wool.
We eight kids like to potter around productively...Mama wants to remember these delightful days when we have all grown up and left home, so we are creating a record for her.
