The yard is already summer, so quite by the way I offer you a master class on the elementary making of multi-colored chalks for drawing on the asphalt! And just need: Gypsum in powder, paints (gouache, temperatures, we have children's paints in a bottle. Tried to use food dyes, but then such crayons are very painted hands), dishes and spoon for mixing, molds.
In a separate container (better than one-time) mix the gypsum with water in the ratio of 1.5: 1. Gypsum add to the water, but will not prompt! To make it easier to observe the proportion, we use one glass for gypsum, one for water. Pour the gypsum into the water
Pretty stirring spoon. The mixture should not be too liquid, otherwise our gypsum is dried. The mixture should not be thick, but thick)) in the instructions for my gypsum the proportion of 1: 1 was indicated, but it was too liquid, so we took the ratio of 1.5: 1.
Add 2 spoons of paint to the resulting mixture (depending on the paint and the color brightness you need).
Well stirred. We work quickly, because if the plaster is properly mixed with water, he quickly freezes
If it allows the age of a child, then all of the above can be given to himself or at least part. My daughter really liked the process, all the crayons, except for the blue, she knew her herself.
Split according to molds. It can be anything. We took a silicone form for ice. Each cell mix the toothpick to remove air bubbles
After 20-30 minutes, chalks are fully prepared for use. You can take them out of the forms and let dry the windowsill in the spring sun, but it is optional!))
Smalls are bright, pleasantly cold. Hands are dirty very, very moderately, some colors do not dock hands at all! I am already silent about the economy of such crayons - plaster costs about 30 rubles for 500 gr, and there are paints at home in all children. We have from this 1 kg bag turned out 50 chalk! And this is on our molds, the gadget cell is pretty deep! In general, consider yourself!))
So nice to draw shameles of our own manufacture! Good luck and you in this simple matter!))
