My dad came from office and we both were bored. Then my dad started it all.He said lets do a project.We used water,a cup,a bowl,a potato, and a lime.First we weighed the potato.it was 91 grams.Then we put the potato in a full glass of water.Some of the water spilled. We had to find out how many grams fell so we used a kitchen scale to measure it.It was 85 grams of water.Then we saw that it sank.
Then we saw if a lime would float or sink.we used the same materials and then we put it in a full glass of water and it displaced 85 grams and we saw that it floated.There is two rules though 1st, weight never counts.Then my dad told me the 2 rules :
- The weight of an object alone does not tell if it will float or it would sink in water.
- More important one, if the object displaced as much as it weighs its own weight that means it will float, if it displaces less water then its weight then it will sink.It is called the law of flotation or the Archimedes principle.
He is really famous. Even after 2000 years since he discovered this law, we still remember him. Wow. wondering what else he found?
