Bubble Wrap Run: Simple Indoor Fun! I used several separate pieces of bubble wrap with duct tape. (side note - duct tape doesn't leave any residue on pergo :)(Make sure to tape down all sides!) The bigger bubble wrap works better than the smaller.
Seidel These are easy to make and allow kids to explore in a variety of ways. Learn colors, explore the Science of liquids, create fun works of art, and engage in sensory play in a mess free way. There is no clean up with these and the FUN never ends.
