Wrinkly Apple

Here's an experiment.

Materials:

• One apple
• One popsicle stick
• One plastic bag
• 1/4 cup of salt
• 1/2 cup of sodium carbonate (powder bleach)
• 1/2 cup of bicarbonate of soda

Steps:

1. Mix salt, sodium carbonate, and bicarbonate of soda together in plastic bag
2. Cut a face into the apple by using the popsicle stick. Push popsicle into the top of your apple so it makes a handle.
3. Put the apple into the mixture in the bag, so it is covered.
4. Leave the bag open, in a warm place. Watch what happens to the apple.

CAUTION: Do not eat the apple once it is wrinkly!
