Chalkboards -- now in a spray! As strange as it sounds, a company by the name of Rust-Oleum has created just that. The product allows the user to turn everyday surfaces like tabletops or wooden walls in a chalk board. One of the best parts of this application is that it can simply be removed with water and soap afterwards.

After the spray has been applied, it works similar to a traditional chalk board, and so it can be used practically for teaching or for fun by doodling. This spray would be especially ideal for children who love to draw all over walls and expensive furniture. Maybe junior will be content with the idea of drawing over the dried spray instead.
