 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. | |
Singing stirings - build a guitarMake beautiful music with some string and a table, and find out why some notes sound great together. |  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. |
Seeing further - DIY telescopeDave builds a makeshift telescope from a pair of magnifying glasses - but be careful not to get dizzy - the image it produces is upside down! |  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. |
Secret messages - what makes an Invisible Ink?How can you make sure your secret letters are only read by the right person? Invisible ink, of course! We show you how to make your own invisible ink using everyday household chemicals... | |
 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. | 
Silver from sootConvert normal soot into a beautiful silvery substance using just a candle, some water and a mug... |
Vortex CannonIf you have ever been too lazy to get up and blow out a candle a few feet away, then we might have the answer. | |

Heat Shrink! - Why rubber bands get shorter when you heat them.Find out what happens if you heat a rubber band and what it has to do with crisp packets and shrink wrap. | 
Fizzes from peroxideUse the power of catalysis to create oxygen and relight a piece of wood, and we give the same reaction a more explosive twist. |
Impaling PotatoesIf you have ever wondered how to impale a potato with a straw? Then this experiment is for you... | |
How useless is a Chocolate Teapot?You have heard the saying, but it is meaningless unless you know exactly how useful a chocolate teapot actually is. We try to find out how thick the walls of a chocolate teapot would have to be to let you brew tea... |
