Designed by a trio of scientists working in Germany (Marcus Rehbein, Asif Karim, and Rolf Eckhardt), this fun and educational website is designed to facilitate the use of balloons in scientific education. More specifically, the site offers detailed instruction on how to create a variety of molecule models out of balloons, such as the octahedron, the diamond, the graphite lattice, and the...

This site contains many chemistry applets created by Jonathan Goodman and his group at Cambridge University. An example of an applet available is the Molecular Weight Calculation; whereby entering in a molecular formula, users are able to discover the HRMS weight, the molecular weight, the element percents, and the Molecular Ion Isotope Pattern. Interactive graphs are also available to assist...
