EXBEPE Physics Optics Experiment Set Prisms Convex Lens Triple Laser Refraction School Light Refraction Reflection Learning Educational Science Kits

Received in good condition. Package is very good Every thing good. But i felt very costly.

This little kit is fantastic for learning or explaining optics. The lens selection lets you show most telescope types, including relflectors. The focal lengths are short enough that you can work on a desk or small table and the laser is bright enough that a small group can see the light path as the lenses and mirrors modify it. I showed this kit to my astronomy club as another STEM outreach project for schools and found myself talked into giving a presentation to the club. To accommodate the small club, I found that a webcam on a tripod can pick up the light paths and lens shapes with a little tweaking. The club was thrilled and couldn't stop talking about it. This was an excellent purchase!

Excellent value, works better than other products.

These got my glasses and held them in place. I didn’t like how long they were and they kept getting caught in my hair when I took them off to show my friend out when I put them back on
