Keeping the kids occupied while on the go can be a challenge. And short of turning into a DVD pusher, your non-digital options can get messy. H2-Whoa is a cool drawing surface that comes with four easy-to-store “pens” that you just fill with water. No messy crayons or markers are needed to create works of art. The portable toy also features a surface on each side, so the board can be flipped over while waiting for the other side to evaporate.
