Lots of children are fascinated by the sky and outer space, and many parents want to encourage their healthy curiosity without investing in the Hubbell Telescope. As a kid, I had nifty glow-in-the-dark stars on my ceiling, but as my parents can attest, they were a pain to install and remove and didn’t have much educational value. Here are a few educational space and sky toys that don’t involve annoying stickers to scrape off the ceiling, no bits of sticky putty to get stuck in the pores of the walls.

Kids will love watching the planets (and Pluto) orbit around the glowing sun from their ceiling with this Solar System Mobile by Uncle Milton. This product does require some assembly and does not fit over traditional ceiling fans or lights. The device is battery operated (the first set is included) and features an automatic 15 minute shut off. This product comes with a educational CD/DVD and glow-in-the-dark star star stickers to complete the space effect.

The Moon In My Room by Uncle Milton is really a neat and educational toy. You simply mount the very realistic moon on your wall and watch as it illuminates through the 12 different phases of the moon. It comes with a remote control or which offers automatic and manual settings. It functions especially well as a fun and educational night light (it automatically shuts off after a half an hour).

This Rainbow In My Room projector by Uncle Milton is another great nighttime treat for kids. It projects a clear, beautiful rainbow across the room, acting as a great night light or decoration. Just like the Moon in My Room, it features an automatic shut off timer and runs on batteries. Plus it comes with a prism to learn how to make real rainbows.
