The last video relates to my own work on density differences in fluids and how they interact with each other.

Will be filming my own experiments shortly and uploading to You Tube.

The above experiments are short videos of simple but fascinating experiments that anyone can try for themselves. First is a trick with a coathanger and a coin that will amaze people.

Second is a lemon battery, which ok it's not a lemon battery more like a lemon generator as no power is put into the lemon but power comes out, and if you connect several lemons together with reversed polarity connections the power output increases.

these would prove great for a classroom exploring physics.

The others, well Ill let you decide

The last one is my favourite, i have never seen or done that one before........goes off to look for a transparent container...

It is convenient that the anti=gravity one is on a white background isn't it - so hard to see the strings....

The "lemon battery" is a battery (strictly a cell- the 2 lemons in series make a battery).
It converts cheemical enery (the energy expended in refining the zinc coating of the nail) into electrical energy.

these are pretty cool also

Andrew, just a few points.

Of the first few you posted i only watched the coke one, the problem (for me) was the long intro of the first, it sort of put me off waiting.
then again, i think microwaves should work faster.

In the "beautiful science experiment", the narrator does mention that It is a trick! Which it is not. Also there is not explanation given as to why the reaction happens.
