This is an oldie but a goodie. My daughter has been on my back about finger painting and I didn't want to go and buy any so I made them with some vanilla instant pudding and food dye a wola, finger paints done cheaply.
What you need
1. 1 packet of instant pudding
Follow instructions on packet, separate pudding into ramekins or container of some kind and food colouring put in fridge to set. Listen to children bug you for 15minutes while pudding sets
Then have fun
