I picked up a "Disney Princess, 3D Chalk Set", on one of those super, end of summer, clearance sales, this weekend. I didn't really expect it to work, but thought the girls might enjoy the stencils, that came with the set. And, since it was practically free - why not?
The set comes with one pair of 3D glasses, 10 pieces of standard, sidewalk chalk, a couple of sheets of princess-like stencils, and some very simple instructions.
Things colored in cool colors will recede, while things colored in warm colors will pop forward when viewed through the 3D glasses. You can almost see it, even without the glasses. But, to my great surprise, the effect is really stunning, when you put the glasses on.
The girls played with the stencils for a while...
...but discovered it was easier to just scribble out a cool colored background, and then draw in yellow, or red, on top of it. With the 3D glasses, yellow things seem to float well above a blue background.
The set turned out to be a lot of fun, and a great way to review cool, and warm colors, as well.
It's great to be a homeschooler.
