Questions & Answers

Q: How does the dry ice experiment make the spoon scream?

The dry ice reacts with the relatively hot fork, quickly turning it from solid to gas and creating vibrations that make the spoon scream.

Q: What happens when using a Van de Graaff generator?

The generator produces a high charge, causing positive charges to build up on the doll's hair. The individual strands of hair repel each other, creating a static effect and making the hair stand up.

Q: How does the plasma ball make the doll's eyes light up?

The plasma ball emits electrical energy, which knocks off electrons from a gas inside the fluorescent light bulb inside the doll's head, producing light.

Q: What other science experiments do they perform in the video?

In addition to the mentioned experiments, they also pour carbon dioxide gas from the dry ice into a candle, and they use a Van de Graaff generator to levitate pie tins.

Summary & Key Takeaways

  • Physics Girl and iJustine perform scary science experiments, starting with dry ice that makes a spoon scream.

  • They then use a Van de Graaff generator to create electrical reactions, causing sparks and making their hair stand up.

  • The video concludes with a creepy doll connected to a plasma ball, causing its eyes to light up.
