WHICH TANK FILLS FIRST? ft. Simone Giertz

Diana from Physics Girl explores a viral riddle about which container fills first. She sets up an experiment with a friend, making predictions and assumptions about the physics involved. They conduct the experiment using strawberry lemonade, encountering some design challenges. The analysis involves Pascal's law, concluding that the riddle is a trick question due to unknown variables. The video ends with a sponsorship message and a preview of future content.

What was the main assumption made about the direction of gravity in the experiment?

• No specific direction

• Downwards

• Sideways

• Upwards

What was used as a visual aid to observe the water flow in the experiment?

• Clear water

• Green paint

• Strawberry lemonade

• Blue dye

What was the main challenge faced during the experiment?

• The water was too cold

• The inlet was too high

• The pipes were leaking

• The containers were too small

According to Pascal's Law, what happens when pressure is applied to a fluid in a closed container?

• The pressure is transmitted equally throughout the fluid

• The pressure is only felt at the point of application

• The fluid compresses

• The fluid evaporates

What is the main takeaway from the riddle experiment?

• The riddle has a clear answer

• The riddle is a trick question with many unknowns

• The riddle is unsolvable

• The riddle is only for entertainment

What is the purpose of the 23andMe service mentioned in the video?

• To sell fitness equipment

• To provide health insurance

• To offer travel discounts

• To help understand personal DNA

What is the significance of the number 23 in 23andMe?

• It is the number of services offered by the company

• It represents the number of countries the service is available in

• It is the number of years the company has been in business

• It is the number of chromosomes in human DNA
