We've been looking for this "classic" science kit for years. Just add salt crystals to laundry bluing and you get a great crystal garden. What makes these crystals so great is their beautiful broccoli-like structure. In nature crystals sometimes take millions of years to form under high temperature and pressure. No pressure required here (maybe a little peer pressure from colleagues who want to know where you purchased the kit!). In just 3 days you'll harvest some of the most beautiful crystals you've ever seen. Great for science projects - the instructions are packed with technical information for those budding young scientists. Take a step back in time with this "retro" science crystal kit.
