Build a sleigh for Santa, which moves down a ramp without force being applied.
This morning, I set my five-year-old the challenge above, and this is what she came up with.
We did encounter a few issues with the first design. The sleigh wouldn't slide down the ramp party because of the friction from the carpet and partly because of the friction from the elastic band on the base.
We decided to make the bottom smoother, so we covered it with sellotope.
This time, it worked perfectly on both the carpet surface of the ramp and the smooth surface.
We also found that if we added sellotape to the Playmobil Reindeer's feet, he slid down easily, too!
