Science and Engineering Week - Day 2. Surfaces

The next one is with mushrooms.
The mushrooms we are using were dried out so we had to add water to rehydrate them.

The mushrooms expanded as they soaked up the water.

For this one you will need an egg and lots of clear vinegar.
Get a jar with a lid then put your egg in it, fill the jar with vinegar (the vinegar needs to be over the egg).
The experiment takes 24-36 hours so I will let you know what happens.
