Product Details

Grow your own spectacular display of long-lasting crystals in gels—using large demonstration bottles! Mix two solutions together to form a gel overnight. Add another solution to the hardened gel, and watch amazing crystals begin to form before your eyes! Crystals become more beautiful over the next two or three weeks! Introduce students to the phenomenon of crystal growing with this easy-to-prepare demonstration. Highly visible potassium hydrogen tartrate and lead iodide crystals are grown—making a perfect classroom display. Kit includes a detailed handout with easy-to-follow instructions.

Concepts: Crystal formation, solutions/solubility, ions.
Setup Time Required: 30 minutes total over two class periods
