Supplies: candies, food powder colors, brush(s), one glass (or a hammer, if you want, but I think it has a too little area to use), a plastic bag.
Put the candies into the plastic bag, close it strongly and crush them, hitting with the bottom of the glass.
I colored the crushed candies with a bit of violet colour powder and then added a touch of gold powder.
This is what it came out.
Thank you for watching :)
