Build a Bridge!

In true Leonard da Vinci spirit build a bridge or structure that does not require any nails or ropes.

Grimm's Spiel und Holz Design, " Grimm's ", has been making beautiful, natural and sustainable wooden toys since 1978. Over the years, I have bought several of their amazing toys, from rattles, to stacking towers to wonderful puzzles.

I love their Leonardo Da toys uses Vinci's Bridge - Wooden Construction Sticks Building Blocks Toy in Rainbow Colors

. This toy was inspired by Leonardo Da Vinci's Self supporting bridge, and the structure when it is built correctly will sustain itself due to gravity.

This toy is a great way to introduce the idea of gravity and of course to test different ways to make a bridge or dome construction.

Due to small parts, Leonardo sticks are only for kids ages three years and up.

Another way to build a self-supporting structure can be seen in the video below. Go here to read more about this model.
