Laser Double Slit Mini-Lab (Make Sure You're Sitting Down)

Regular price $15.50
This Mini-Lab includes everything you need to perform Thomas Young's classic double-slit experiment that demonstrates that light can behave as a wave.  Included are:
(1) One 3-in-1 key chain that includes a 5Mw laser (details below)
(2) 12" of black electrical tape
(3) 6" of 32 gauge wire
(4) Straight-forward step-by-step illustrated instructions (for an adult) so that you can easily and successfully perform the double-slit experiment at home in less than 10 minutes
(5) A kid-friendly explanation of the experiment
The included 3-in-1 key chain is better than you normally find in Canada - it has a red laser pointer, a UV torch, and an LED white light! You can choose the colour of laser that will come with your kit: there are 6 colours - green, black, purple, red, blue and silver. All pointers are 5Mw and have a nice high power, strong, long lasting beam! Besides the double-slit experiment, it's also great for presentations, cats, pets and emergencies!
