Harness the power of the sun to pop a balloon inside a balloon with this experiment from Jason Lindsey.
PLEASE follow these safety precautions when doing any science experiment.
• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything while doing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
• Magnifying Glass
• Black Balloon
• Clear Balloon
STEP 1: Push the black balloon inside the clear balloon. Inflate the black balloon. Tie the black balloon.
STEP 2: Inflate the clear balloon, so the black balloon can move freely inside the clear balloon. Tie the clear balloon.
STEP 3: Using the magnifying glass, focus a beam of light, from the sun, through the clear balloon, to the black balloon, and observe. Describe what happens when you place the balloons in the path of the beam of sunlight. Provide evidence energy was transferred to the black balloon by the beam of sunlight.
The black balloon quickly pops, while the transparent balloon stays inflated. The magnifying glass allows you to concentrate a beam of sunlight through the transparent balloon to one spot on the opaque or black balloon, which eventually weakens the rubber, causing the balloon to pop. The black balloon absorbs the beam of sunlight causing the balloon to heat up, weaken, and pop.
