Bubble Painting

a) Theory: Bubbles
Q: Will coloured bubbles such as pink bubbles be pink once blown?
Q: When we use different shaped wand such as star shape, will bubbles blown be star too?
• Water has got a thin surface tension. That explains why little bugs like Daddy Long Leg could stand on water surface.
• Bubbles = Water + Detergent. (+ glycerin……added in sold products)
• Detergent strengthens water surface tension. When blown, it bursts after a while.
• Bubbles are colourless but we can see the rainbow reflection on them. Even coloured bubbles will be colourless when blown.
• I brought out some wires and showed the kids a few shapes that I could bend out of the wand. Weei Xiang also tried bending one. I didn’t make it an activity for kids to bend as the sharp point would be dangerous. Result: Bubbles blown are still circle!

b) Bubble Painting
• Paint + Detergent + Water = Bubble Solution.
• The paint needs to be mixed well with the detergent before mixing with water. Each kid was given a straw to blow the solution to the maximum. Then, kids quickly place the white paper over the bubbles to gain the burst patterns. We made 2 colours; black and pink. The kids took turn. They were taught to blow before the real painting. Most of the kids were independent.

c) Cartoon Movie: Rio
• Zhi Feng shared this film with us. Everyone has been talking about the iPad’s Angry Bird. And the kids love the Rio song as their dance background. Thus, we decided to watch Rio hoping that the kids will realize that birds can be happy too!  We watched only for a while….to be continued.
