My science fair is about how does the temperature effect its strength. The hard thing about this was trying to connect the Dyna screw to the boiling magnet. My procedure first I heated up one magnet for an hour on 100 degrees Celsius, and another one in the freezer for an hour and left one in side. Then I put one hundred paperclips in a glass and attached a dyna screw to a magnet and dipped the magnet in the glass with all the paperclips.
