My 3rd grade students had fun investigating the properties of light with these prisms. I wish they came with a soft storage bag individually.

I am sorta a mystery Santa (except I’m older than Santa). I live in a complex where there are some struggling families. I buy the kids of those families something educational or musical for the holidays. I give them to the parent/parents to give to the kids. This year it’s the prisms.

Un prisma de 15 cm y otro de los pequeños de 6 cm venÃan con una arista dañada. DebÃa venir todo el luego en un estuche con protección. Probé con una linterna pasándolo a través del prisma y la verdad nove muy bien que descomponga los colores.

These prisms worked wonderfully. They are the perfect size for students. My class had lots of fun making rainbows as part of their science unit.

Ordered multiple boxes and there were several broken or chipped crystals in each box.

Needed for my classroom and couldn’t use because the edges were so sharp and dangerous.

These are the light of my life! There are many projects, which these prisms can be applied to! Why should schools have all the fun? Combined with lenses, rainbows can fill the room!
