The Bathtub Trick That Went Viral (SergeyMaster1)

This man went viral for his clever method of using a bathtub to speed up concrete mixing, and now he’s about to build a concrete step in just 30 seconds. First, he mixes water, cement, and additives with a concrete mixer. Then it’s time to add sand. After mixing again—watching it is oddly satisfying—he adds even more sand and keeps mixing until the blend is perfectly uniform for maximum strength. Now comes the gravel. It might seem like too much at first, but as he mixes thoroughly, the concrete fills the bathtub just right. Finally, he starts pouring the concrete to form the foundation, and thanks to its ideal workability, it fills every gap smoothly. He finishes the top with a float to level it out, and here’s the impressive final result.
