Kids science - Toys trapped in frozen eggs.

The kids had loads of fun with these frozen eggs. They decided they were going to have a competition as to who was going to unfreeze and rescue their toy first. 

To create these frozen eggs you need some water balloons, small toys, water and a freezer :)

First pull open the balloon as much as possible and carefully put the small toy inside.

Carefully attach the end of the balloon onto the tap and fill with water.

Tie the balloon and place it in the freezer.

Once the water has frozen cut the balloon and place the frozen egg into a plastic container.

Mix some warm water with salt and add some food colouring.

We then used the salt solution to help melt the ice. They used the pipette to pick up some of the solution and put it where they wanted it to melt.

They added more salt straight onto the frozen egg and then added more solution. This caused the salt to fizz and the ice to melt quicker. 

They were completely involved in the activity for over 30 minutes. Middle boys toy was rescued first closely followed by Toddler girls.
