Crayola has a new Spira-Chalk Blaster. You can watch our video demonstration. It comes with five chunky pieces of sidewalk chalk and two spinner rings–that fit into the launcher. We loved the fact that the launcher does not require batteries and that it really does create a spiral design on the sidewalk. With the exception of one of our testers, we got positive feedback on this product. (One tester found the release mechanism difficult to work–we think she got a dud.) We wish that it came with two launchers so that two kids could use it as the same time…but for $15.99–it’s still a good add-on if sidewalk chalk is big in your neighborhood.
