Magic Sand

Magic Sand begins as normal looking sand, until it's dyed and coated with a substance that repels water. This coating keeps the sand dry ... all even after it has been dumped into a container of water. Build castles and other structures under the water, then simply pour the water off when you're finished and the sand is still dry! You can use it for fun science experiments again and again! Colors vary!
I have heard that it can be found all over Florida in sandy inland areas.
I really want to see and touch this sand .Have you seen this Magic Sand anywhere?
