I have a degree in Geology so of course I love crystals. They are so beautiful in their myriad of colors, shapes, and sizes. The most common type of crystals we see are ice crystals (solid water). The kind of crystals you see in rocks (like those in geodes) form under very specific conditions where molten rock cools slowly over a long time. In today's experiment you will made a kind of crystal that still grows slowly, but over days, not years. And best of all, you can eat it! In this experiment you will be growing sugar crystals. For a bit more fun you can add a flavoring or color, but neither are needed as sugar is great just by itself. Make sure you do not skip the first step - getting some sugar crystals to attach to your stick - crystals need something to start growing on and then they repeat that initial pattern as they form. Materials:
Parent tip: Once you remove the rock candy on the stick, you can re-heat the remaining liquid/crystals that are left in the glasses for another batch. Instructions & Video: Here is the link to the instructions and video. Thanks to TheSpruceEats.com. What's Happening: Here is a link explaining why it works.

welcome!
Every school day I will post a new experiment for you to try at home. Some may be familiar to you - as they are my favorites from class - but most will be experiments I found on the web that have readily available materials. Happy Sciencing! Earn a Patch
