How Do Suction Hooks Work? | BYJU's NWK Shorts

Suction hooks are like the wizards of the organizing world. They stick to smooth surfaces like a gecko on a wall, using the power of suction to stay put. You can hang your towels, loofahs, and even your rubber ducky on them, without drilling holes or damaging walls. They're simply amazing at making any place look neat and tidy in a snap!

Watch this NWK Shorts episode to understand how these sticky wizards work!

[MANIKANDAN-dsoh]

cement surfaces are typically rough and porous, which means that air can easily flow in and out of the surface, preventing a vacuum seal from being created. This can make it difficult for a suction hook to stick to a cement surface mam

[findramen]

Suction Hooks does not work in cement surface because cement surface is not plane and smooth. Suction Hooks works in plane and smooth surface.

[merazashraf]

Because cement surface has so many microscopic space containing a lot of air balancing air pressure

[rohinisantra]

The sucker sticks to the surface because the pressure of atmosphere acts on it.Cement tends to have a rough and porous surface which will cause the vacume to fail. Incase of rough surface all the air between the cup and the surface does not escape and exerts pressure on the inner walls of the cup, hence it does not stick to the surface.

[debangineesamal]

Because the surface is rough and the suction hook doesn't lie even. Due to which some the some air enters

[tavishicreation]

Because it has holes in it which allows air to pass through it and it is also uneven surface

[artavengerskavitha]

due to the regularity in the cement surface the are might enter through the pores

[Leo-yggm]

Because there are air molecules present in there cement... which does not allow suction?

[poonammakhija]

Suction hooks Don't work on cement surfaces because they are rough which means air can go in and out

[deepraj]

Because it stuck only smooth surface but cement is rough surface 😊

[SpectraNest]

Maybe because the cement surfaces have small pores

[salmaansari]

Because cement wall are rough and porous

[saanviroy_]

They don't work on cement surface because the cement let air pass through it as it has tiny holes. The air pressure doesn't slow down as the air is coming from the holes in the cement surface.

[rahultiwari]

Because cement is not leveled and has pores/gaps which allows air to go through and suction hooks can't hold firmly

[ZafarMalik-mvcc]

All the air between the cup and the surface doesn, t escape ut and exerts pressure on the inner walls of the cup this it do not sticks to the surface

[seekshagovindrao]

Because cement surfaces are rough allowing air to pass in suction Huck which hinders the working of suction pressure

[varshinivisali]

Cause cement surfaces are rough so the sticky surface of the suction rook cannot stick there

[riturajthakur]

Because of large space gaps on surface of cemented area

[sanketkulshrestha]

Because cemented surfaces are not smooth and Air can go in the hook again.

[shadowcosmos]

I think in cement due to those pores the perfect vacuum is not created inside suction cup
