Home Made Paint

Ingredients
1 Egg Yolk
2 Tablespoons Water
1/3 Tablespoon Vinegar
Food colouring

Start by cracking the egg and separating the whites from the yolk, use your hand to catch the yolk because you need to wash away all the egg white from the yolk under a gentle warm running tap.
You can use your left over white Here.

Please excuse my blue hands there was a toddler + food dye incident today....

Once your yolk is washed, try drip away as much of the water as possible.
You now need to break the yolk sac with a sharp knife and let the yolk drain without the membrane. (throw away the membrane)
Mix with a folk and add water and vinegar, once well combine add food colouring. (if you want a very bold colour cut back on water to make up for the extra food colouring so you don't dilute the paint) 

Done!
