Below is an simple experiment for you to do with auto body filler:
- Make a simple mould by pressing a coin or some other pattern into plasticine (modelling clay). Carefully peel the plasticine away and mount it on a flat surface with the image of the coin facing up..
- For the next part you should wear gloves, and work on some newspaper so you don’t make a mess, and get an adult to help you..
- Following the directions on the pack of body filler, you mix a tiny amount of hardener with some (monomer) resin. Mix it really thoroughly so that you make a good reaction..
- Carefully spread the mixed up filler over the plasticine mould..
- While the filler is going hard, gently feel the temperature. If it is warm, it is a sure sign of a chemical reaction taking place..
- Leave your filler to go really hard. If you try to look at it too soon you might break it..
- Carefully peel the plasticine away, and you will have your own reaction moulded article.
Good Luck!
