You can use this bubble effect on many things I have used this effect on ceramics and paper if you find another use for it please comment below!

Supplies

Tiny cup, 1 squirt of blue paint, 1 squirt of soap, water, and the thing you want your bubble effect on(Ceramic, paper, etc)

Step 1:

Take your cup and add your soap and paint. Stir it until it's all mixed up. Add the 1/4 tsp of water and stir until the water becomes blue. Now take your straw and put it into the water. Start blowing bubbles into the cup. Continue blowing bubbles until it starts dripping over the edge. Gently lay the bubbles onto the object you want a bubble effect on. Try to not pop the bubbles. After a few minutes, they will pop on their own and leave a bubble effect. I suggest that you don't do multiple layers or else they will look messy.
