Biking Across a Pool of Cornstarch Beats Walking on Water Any Day

The minds behind theHard ScienceYouTube channel have give us a crash form in the exciting earthly concern of non - Newtonian fluids in the most amazing way possible — by bicycle across a pool of cornstarch that is , at once , both solid and liquid .

By creating a mixture that ’s two section cornstarch to one part weewee , the squad was capable to produce a liquid state that in reality changes its viscosity according to the amount of force applied to it . So just like in the cornstarch wonderland above , you’re able to really walk on a liquidness so long as you move tight . The ground this is possible ?

In non - Newtonian fluid , the subatomic particle are packed very close to each other ( they are affecting ) , but they are still able to slip by each other . When you move the salmagundi slowly , the suspend particles have time to move and slip by each other — this is how a normal liquidity act . However , when you suddenly apply pressure to the mixture , the speck do not have enough time to move out of the way as they are quite large . This causes them to abide right where they are which causes the mixture to roleplay and feel like a unanimous .
