Often friends come home and you don't know what to do, maybe you don't know how to entertain children or you just want to take an original photo, here I leave a simple recipe of colored powders, with only three ingredients. It comes out easily from the clothes and it is not toxic, it is convenient to do it 1 day before the visits but it's really worth doing it.
Put one or two teaspoonful of water into a glass and add the colorant.
Step 3: Add the Cornstarch
Add two or three spoonful of cornstarch (depending on how much water you put) and mix.
Step 4: Do It Again With the Rest of the Colors
Repeat the same process with all the colors
Step 5: Let Them Dry
Let them dry for one or two hours (approximately) in the glass.
Step 6: For Perfect Drying
Put two or three napkins on a flat surface and pour the mixture. The napkins will absorb water. Let them dry, preferably in the sun or in a warm place. I waited three days for it to be completely dry, but with one night or it would be enough if the proportions of water were not abundant.
Step 7: Move to Different Glasses
Once dried, pass them to 7 different glasses so that the colors do not mix.
Step 8: Crush the Grains
Use a rolling pin or a grinder to crush the grains until they become a power.
Step 9: Photo!
Put a spoonful of powder of the color you want in your hand and blow it for a photo.
