 Mysterious forces - Eddy CurrentsHere is a lovely little experiment you can do if you can get hold of a small rare earth supermagnet. Using just a couple of tubes you can produce surprising forces. | 
Cloud ChamberA really classic physics experiment that helped to understand some of the most fundamental particles in the universe. |
TEA Laser - How lasers workThe homemade UV TEA nitrogen laser is very dangerous, but useful to understand how a basic laser works. |  Rubens' Tube - waves of fireOne of the most beautiful and impressive physics demos is Rubens' tube, producing waves of fire that dance to the sound coming from a loudspeaker. |
Flame Tornado - A Spinning Column of FireThis is one of the most beautiful science demos out there and always makes a big impression, creating a pillar of spinning flame and explaining how a hurricane is formed. | 
How fast is a sneeze?This time of year coughs and sneezes are a common complaint, but just how fast is a sneeze. |
 Dark FlamesIt sounds like something out of a horror film, but this is a lovely experiment which makes a bright orange flame seem dark, and has lead to scientists finding out the composition of stars on the other side of the universe. |  Electricity from water - Kelvin water drop generatorThis is a beautiful little demonstration dating back to to Lord Kelvin. Using a few cans wires and dripping water it is possible to generate thousands of volts in a beautifully elegant piece of physics. |
 The Barking Dog ExperimentThis is a classic chemistry experiment dating back to the 19th century with impressive, loud and sometimes explosive results. |  Phosphorus MoonDr Hal brought along another classic chemistry experiment, the phosphorus moon, with rather beautiful results. |
 Exploding Eggs - Burning HydrogenHydrogen is an extremely flammable gas, but what happens if you fill an egg with it, light the top and retire to a safe distance? |  Light Bulbs in Liquid NitrogenWhat would happen if you put a light bulb in a bucket of liquid nitrogen? And would it still work if it were just a filament? |
 Dry Ice Experiments and BombsDr Hal showed us some things to do with dry ice; including the highly dangerous dry ice bomb. |  Why does a pigeon's head bob as it walks?Pigeons and various other birds seem to bob their heads backwards and forwards in a bizarre manner, which seems to be a lot of hard work. I was watching some in front of my garage and dug out the high speed camera to see what is going on. |
Liquid Nitrogen BombOne thing you should never do to liquid nitrogen is to seal it in a pressure vessel.... so we had a go. | 
The GherkinatorHave you ever wondered what would happen if you passed mains electricity through a gherkin? It is an illuminating experience. |
 A cornflour monsterThis is a really strange effect only discovered about 6 years ago. Basically it involves shaking cornflour mixture very hard and it starts to grow tendrils, in a very 1950's B-movie way. |  Cello vibrations and how a violin bow worksFor this week's kitchen science I took some high speed footage of some cello strings but there were some fascinating effects which didn't really fit into the kitchen science, so I thought I would post them here. |
 Colour Flashes from light bulbsEver since I acquired my own high speed camera (after an unfortunate incident with a borrowed high speed camera and an exploding pumpkin) I have been pointing at things which may be interesting. Last week I tried light bulbs as they turned off with some quite colourful and fascinating results. |  Settling snowJust quickly, I was looking out of the window one afternoon last thursday and noticed how snow was just settling where cars used to be parked, which seemed quite strange because one would have thought that a car having been parked over the tarmac should be warm and make the snow less likely to settle. |
 Acoustic LevitationHere is an interesting effect I noticed a couple of years ago. I was actually attempting to smash a wineglass using sound. I was using a piece of paper to detect when the glass was nearing resonance, and accidentally discovered something altogether more fascinating, the paper started to levitate. |
