@bruhmomentummoment: The technique used in this test is called hydraulic cement patching, where a fast setting cement mixture is pressed directly into an active leak to displace the water and cure in place. Widening the crack slightly before applying the patch creates a better surface for the mixture to bond to, since a narrow gap doesn't allow enough material to fill in and create a seal strong enough to hold against water pressure. The waterproof additive mixed into the cement accelerates the set time and improves adhesion to wet surfaces, which is critical when the material has to cure while water is actively pushing against it. The test is designed to simulate real emergency plumbing scenarios where water can't be shut off before a repair has to be made. #engineering #construction #plumbing #china

Use your palm is the trick like don’t cup your hand flat and firm where your pal covers the hole not fingers either.

Firdous :

Wasting water

Dogbowl :

Use bread

🔻Kekero (level 13 Wizard)🔻 :

You need to be directly in front of it or else you don’t have enough leverage

Anthony :
