What Kind of Liquid Lets You Run Across Its Surface? | Street Science

Street Science | Wednesdays at 10/9c on Science
How can it possible to walk or ride a bike across the surface of a liquid? Kevin and his crew have created a goo that acts as both a liquid and solid.

I just realized this would be great defense against zombies

Imagine being in a marathon, but you're tired so you stop running for a moment, and you start sinking into the path

[superligitguy]

Imagine if there was an ocean of this stuff and you somehow became stranded and the only way to briefly survive was to continuously move until your body gave out. Nightmareessss

[mrupsetti]

Imagine a sport played on this stuff, and if you fell into you were out or something

[kittyyoutuber]

Imagine if the dude who was doing cartwheels got stuck in the pool headfirst.

Instead of telling people not to loiter, stores should just have oobleck moats so nobody can just stand around

[mooonblooom]

jeez oobleck is so hard to clean up because it always hardens up when i try pushing it off

[pauldeddens]

I would love to see a game of soccer with a field made of this stuff
that would make it so much more interesting

[kernowg]

What has this mans drain pipe been through? I imagine it being a drain pipe equivalent of a war

[kevster]

Oobleck is not considered a liquid. It is a non-newtonian fluid.

Downward force rather than a spinning wheel is what firms up the liquid. They wrongly state that pedaling hard would help. It doesn't. Consistent downward force is what is needed, not forward spinning rear wheel

They harden in response to physical trauma

[hoss]

The reason why the biker sank the second time is cause he was trying to show off

[TKOh-ttoi]

Really cool seeing a bike being able drive across what looks like liquid, unless you started peddling from a standstill, in which it just results in getting Artax'd.

[KeillorChristopher]

There is a really fun science experiment if you could find someone with a mud bogging truck it wouldn't mind if it blew up or died but make a Oobleck pool big enough for the truck to go in let it sink and see if it has enough torque to pull itself free and how much torque would it take

[brendethedev]

Imagine build a house in the middle of a oblec mote. The only way to get to the house is to keep walking.

[DestructionChannel]

this stuff is surprisingly hard to move through if you let it sink in at all

[sheppybread]

Its not a liquid, its not a solid, its a LOLSQUID

[theproblemmustbeinyourpant]

It would be the most sadistic thing to trap someone in a really tall tub tub with 8ft of this stuff in it.

1:00 Torture chamber idea #1:


put man in room, all oobleck, tell them if they stop moving, they die


they will eventually become tired, and cease movements


they then die from drowning
