Grow Your Own Crystals

This kit gives you everything you need to run a safe scientific experiment in your own home where you can grow crystals, clear or colored. Simply add vinegar and watch the crystals grow over a few days. Add food coloring to grow colored crystals. Fun for children and adults alike! Makes a great gift idea.


1 Put Rocks into smalt dish, all together If you want them all the same color, or a separate dish for each color.   
2 Pour enough distilled white vinegar (from grocery store) to just cover the rocks as shown in the picture. Do not top up with any more vinegar than that. Crystal garden instructions 1 
3 Leave dish in a safe place in a WARM room (A windowsill is NOT generally warm).  
4 Your crystals will begin to grow within 2 days, but can take up to 2 weeks. Growth will continue until all vinegar has evaporated. Once you have a good crop of crystals, but before all the vinegar has evaporated, add a drop of food coloring of your choice to the vinegar. This will gradually seep into the crystals. With a selection of colorings, you will soon have your own colorful 'Crystal Garden’. Crystal garden instructions 2
When all the vinegar has evaporated, do not add more vinegar. Leave for seven more days allowing the rocks and crystals to dry and harden. Remember to handle them carefully.
