Balloon Molecules
Two  chemistry PhDs and a balloon sculptor in Germany have created an entertaining way to visualize atomic particles and structures. Using modeling balloons and a few twists, they've designed simple tetrahedrons and giant DNA helixes to demonstrate math and chemistry lessons. And they hope educators around the world will give it a try. Animations and photos illustrate all the basic knots, so you can tell a saved pinchtwist from a tuliptwist. If you get stuck, the FAQ helps troubleshoot problems like balloons that burst when you build with them. At last, the fine art of the poodle knot may be recognized for its contribution to science!
