It looks like sand art but it is actually salt!!!
THE CONTENT OF THE JARS WILL NOT BE EDIBLE!!!
Step 1: Things You Will Need
-2 Jars (one for mixing the colours and another for putting the salt in)
-Coloured Chalk (they can be any colour you like)
-A Funnel (This is completely optional, I just used one so i wouldn't get the salt everywhere. If you don't have one you can easily make one out of paper! Make a cone shape and tape it together, make sure the tip of it isn't too small or else the salt will get clogged up.)
