It's true perfect specimen-quality crystals can take some dedication to produce, but if you want crystals and you want them now there are projects that give instant gratification. In addition to being quick, these projects are also safe for kids. 01 of 06 Cup of Crystal Needles Grow a cupful of epsom salt crystals in your refrigerator. It's quick, easy, and safe. 02 of 06 Borax Crystal Snowflake These crystals grow overnight, but if you start them right before you go to sleep, it's almost as good as instant crystals. 03 of 06 Quick Sheet Crystals This project will ice a pan with a sheet of crystals within seconds. Very fast, very cool. 04 of 06 Crystal Spikes in the Sun The instructions, as written, call for evaporating the crystal solution on construction paper, but I prefer to use thinner and less-colorsafe tissue paper for quicker and brighter crystals. 05 of 06 Salt Crystals You can use heat for force salt crystal evaporation. The water evaporates and rings form while you watch. 06 of 06 Alum Crystals Alum crystals grow quickly. You should see results overnight.
