Exploring the Myth of Walking on Water

In this video, Adam attempts the mythical ninja trick of walking on water using a mixture of water and cornstarch. The experiment involves creating a non-Newtonian fluid that allows Adam to run across its surface without sinking. The video explains the science behind non-Newtonian fluids, highlighting how their viscosity changes under stress. Despite the success of the experiment, the video concludes that the idea of ninjas using such a method is far-fetched, though it was a fun and educational experience.

What was the initial result when Adam tried walking on water?

• He completely submerged

• He partially sank

• He walked successfully

• He floated

What ingredients are used to create the mixture that Adam attempts to walk on?

• Water and salt

• Water and sugar

• Water and cornstarch

• Water and baking soda

What type of fluid is created by mixing cornstarch and water?

• Non-Newtonian fluid

• Newtonian fluid

• Viscous fluid

• Incompressible fluid

How does Adam successfully cross the mixture?

• By jumping

• By running quickly

• By crawling

• By walking slowly

What scientific principle allows Adam to run on the mixture without sinking?

• The fluid's low viscosity

• The fluid's high density

• The fluid's change in viscosity under pressure

• The fluid's temperature

What happens when Adam stops moving on the mixture?

• He continues to stand on the surface

• He begins to sink

• The mixture turns solid

• Nothing changes

What does Adam describe the feeling of stepping into the mixture?

• Pleasant and soft

• Sticky and uncomfortable

• Funky and wrong

• Slippery and cold

What historical context is given for the use of cornstarch in feudal Japan?

• Cornstarch was unknown in Japan

• Cornstarch was commonly used by ninjas

• Cornstarch was used in building materials

• Cornstarch was introduced around the 16th century

What is the final verdict on the myth of walking on water with cornstarch?

• Plausible

• Unresolved

• Confirmed

• Busted

Why is it unlikely for ninjas to have used cornstarch mixtures?

• Ninjas did not have access to cornstarch

• Cornstarch was too expensive

• It requires a large quantity to be effective

• Cornstarch does not exist in liquid form
