For this we need a peice of steel. (make sure the item you will be stiring does not react with steel)

Earth magnet (obtained from hard drives or can be bought on ebay fairly cheap.

Small motor
__________________________________________________ _________________

attach the magnet to the motor using your own method

Place the steel into the product you will be stiring

make the motor turn over to make the steel turn around
this mixes it (obvo)
you could turn this into an auto -matic item to do this throught the day if you have the brains to do this.

one problem with that, chemicals involved in explosive making often react violently with metals, but i will give you credit that is a great idea. you need to coat the steel in something less reactive like glass as long as your not mixing hydrofluoric acid with the glass coated steel you will be fine

gd idea ill look into this thanks man, ill post back with my findings

What about using two magnets, one coated in a non-reactive materal, one attached like above, that way, you can reduce the risk of using steel in mixtues.

Wouldn't the problem there be length?

i dont think so, if the contaner is thin enough, both magnets (depending on power) would stick to eachother, and as the bottom one spins so does the top. im just floating ideas here, if i were to design a chemical mixer, it would A.) run on a timer, B.) be made of all plastic, or glass/ect and, C.) mix from the top useing a slow or multi speed moter

You are FUCKING RETARDED. This is known as a "magnetic stirrer".

It exists. Chemists use them all the fucking time.

What are the pros when comparing this to a normal electric stirrer.
