- Two demonstrations of the properties of sulphur hexafluoride, a gas 6 times heavier than air. In the demos, you'll see how the gas affects your lungs (Compare with what happens when you inhale helium!) and how it supports the weight of a small tinfoil boat.

- A neat video that shows some of the strange properties of sulphur hexafluoride, a gas 6 times heavier than oxygen. Who would have thought gas could be so fascinating.

- this is truly cool science. but i understand SF6 to be like 22,000x more potent a greenhouse gas than CO2. so play safely.
