Does Water Really Swirl Differently in Australia? YouTube Stars Find Out

Smarter Every DayandVeritasium , two of the secure scientific discipline channels on YouTube , have teamed upto result once and for all : Does water really hang the other way in the southerly hemisphere ?

Destin Sandlin , host of Smarter Every Day ( based in Huntsville , Alabama ) and Derek Muller of Veritasium ( who ’s in Sydney ) each filmed a video from their several hemispheres to MythBust this oft - quoted scientific choice morsel . The two vids are meant to be watched in sync , and are shoot in such a means that the dialogue , music , and effect mesh up as though it ’s one video .

It ’s a quislingism the YouTube champion have been planning for three years , and we ’ve implant the vids here on one page for your widget . insistence act as on one video , suspension at the sync mark , start the other one , and re - begin the first one when they both oppose up :

In the guys ’ experimentation , they each filled a kiddie consortium with water . They did n’t want to just go off tubs and toilets — there are too many variable quantity there . Toilets have jets in them that influence water system flow , and no matter where you are on Earth , there will be toilets and sinks that drain clockwise , and others that fall counterclockwise .

Each kiddie pool was filled and allowed to sit down for 24 hour . Then the guys pulled plugs from underneath each tub , dropped in some food for thought coloring for visual aid , and waited with bated intimation .

The results ? Water did indeed drain counterclockwise in Alabama , and clockwise in Australia . As the Earth spins on its axis , it pulls water in different directions depending on where you are . We can see this in nature with the Coriolis outcome : hurricanes in the northern hemisphere spin counterclockwise , while the Dixieland ’s cyclones whiplash clockwise .
