How about a spot of halloween chemistry? With nice simple explanations for the trick or treaters.
- Golden syrup

- Bicarbonate of soda
- Grease proof paper
- A baking tray
- A saucepan
The toffee mix gets very hot, be careful when handling in and make sure there’s an adult helping.
What to do:
5. Carry on heating until it reaches 145-150oC (293-302).
9. Break it all up (best done with a hammer) and enjoy!
