Baking soda snowballs

I have been meaning to post this, but always got distracted. Ok peeps, here it is.
I wanted to do a fun science project with the kids and found this on a blog, but now cannot remember which one . There is a YouTube video that shows how. Not sure the exact link.
The kids really liked this a lot .

You will need the following:
1cup of baking soda
1/4 cup of water
Small toys or whatever you want to hide in the snowballs.

Take a cup of baking soda and pour it into a large bowl and add the 1/4 cup of water.
Have the kids use their hands to mix it together. (Some kids loved, others did not)
If there is to much water, add more baking soda , to much baking soda , add more water.

Next, pack a layer of baking soda mixture into the bottom of a muffin tin. The kids can then put a toy on top of the baking soda.
I then added more baking soda on top of the toy.

Turn oven to 170degrees. You do not want to melt the toys.

Then bake them for about an hour to let the water drain out.

When the hour is up and the snowballs have cooled, put the snowballs in a bowl of vinegar and it will bubble and explode and the toy will reappear.

-my kids really loved this and it. It was a good science lesson about the process and why baking soda will bubble in Vinegar. We had some great discussions.

Hope you enjoy it. It was really fun!
