Fun with Chemistry

Low-field NMR
Using the low-field NMR spectrometer that we have originally constructed for our Physical Chemistry lab class, we can demonstrate the principles of NMR. Would you have guessed that - in case you do not like reading the labels on soda cans - you can also use the NMR signal to tell the sodas apart, without even opening the can? picture 1

Cronstarch Oobleck
Cornstarch Oobleck is a liquid with puzzling properties. Consisting of 40% water and 60% cornstarch, it becomes a solid when put under any kind of stress. It can be rolled into a hard ball, but as soon as you cease rolling, the ball will "re-dissolve" and flow out of your hand. picture 3
