On our science day we were investigating the power of heat. the challenge was to pop a black balloon that was inside a clear balloon using only the energy of the sun and a magnifying glass. The only problem was there was no sun. Today the sun came out and we tried it and it worked!!!!
Using a torch and magnifying glass.
After the sun did its work, the black balloon burst. This is because black absorbs the heat quicker than the clear balloon.
