Rainbow Building SticksRainbow Building Sticks are simple sticks one can create a dome and a bridge, which stand without glue or a cord and without a nail or a screw! Admittedly, one needs a quiet hand and some finesse to set it up. The beauty of it is, that you can start with one or two modules, which can then be extended step by step to become a larger bridge or dome. Combine the Sticks with other building blocks, creating stairs, bridges, houses and other buildings! 100
