Sup y'all! Just read this instructional on how to make crystals on here this morning perfect for a DIY Home experiment for you and the kids, simple enough all the gear required is found around the house. If not it's super cheap to find, all you need is the following.
Some coins (5-10), 1 straw, 1 jar / cup, some bleach, some ammonia (found in things like bathroom cleaners), baking soda, and salt.
Step 1: put 2 tablespoons of salt and 1 tablespoon of baking soda into the jar
Step 2: Pour the ammonia 2/3 the way full into the jar
Step 3: Pour bleach the rest of the way up
Step 4: Put the coins into the jar
Step 5: Grab your straw quickly and start to blow directly onto the coins
Step 6: profit!!
You should see the crystals start to form up after about a minute or so of blowing, if you stop however the crystals stop forming. It'll take about 10 mins to actually get decent results.
Attached picture is the one me and my 6 year old did today, she's inlove with it (comes out basically identical to glass).
Science is always great fun to get the kids into early in life.
