🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
If it bubbles, something invisible is escaping.
Mind = Blown
💧 Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.
Make a hypothesis first
Guess: will the fizz be loud, soft, or none at all?
What You'll Learn
Thermal energy transfers from warmer objects to cooler ones through conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves).
