I'd like to apologize for my last instructable to those of you saw it before I deleted it. Also to Tetranitrate, I'm sorry for posting an instructable similiar to yours and thank you for not "blowing up" over it, instead you chose to tell me how to create the iodine crystals. I admit that I forgot to search to see if there were any such instructable already made and was so proud of how well I had written it, that I immediately posted it.
Now onto this instructable. You can turn metal (as long as it is attracted to magnets) into a magnet for a temporary time. This is a neat little trick you can do at home or any other place. Teach your kids how to do this, so then they might be interested to learn more and may even some day grow up to become a mad scientist. This is also fun to try and see how strong you can make the temporary magnet. Hey, you could even use this in a science fair.
