Make a miniature version of a chip packet. You could make this into a keyring to hang on a school bag.
What you need:
- 2x baking trays
- baking paper
- chip packet
What to do:
- Wash the empty chip packet with dishwashing liquid and water. Dry it thoroughly. If you want to make a keyring, put a hole in the top corner.
- Put the chip packet on top of a sheet of baking paper on a tray. Place a second sheet of baking paper over the top.
- Place the second tray on top to keep the chip packet smooth.
- Bake at 180°C for 10 minutes.
- Remove the top baking tray, wait a minute for it to cool slightly and remove the chip packet. You will now have a miniature version.
What happens:
The chip packet is made of polymers – long chains of molecues. They are stretched out to make the chip packet. When the chip packet is heated, the polymers bunch back up, causing a cute miniature version of your chip packet!
