Hooked On Science: Toaster Hot Air Balloon
Toaster Hot Air Balloon
INGREDIENTS
- 30 Gallon Clear Trash Bag
- 4 Slice Toaster
- Large Tub
INSTRUCTIONS
STEP 1: Place the four slice toaster into the large tub. Plug the toaster plug into an electrical outlet.
STEP 2: Turn the toaster settings to the highest and push down the levers until they lock.
STEP 3: Place the open end of the 30 gallon clear trash bag over the large tub. Hold the trash bag until it completely fills with hot air. Feel the sides of the trash bag. Are the sides hot or cold? Why? Let go of the trash bag. What happens? Why?
EXPLANATION
The flow of rising hot air from the toaster creates a convection current inside the trash bag. As a result the air is heated, the trash bag expands, become less dense, and eventually lifts into the air.
