Review on Optical Spectrum Physics Teaching Novelty & Gag Toys by Greg Baker

Revainrating 5 out of 5

Grandkids learned a lot

I got this to show my grandmothers and distract them from online games. Worked beautifully and now it sits on my glass shelf by the window and puts on a show on sunny days.

Pros
  • Show your kids a rainbow
Cons
  • There's nothing here
