Put on your thinking cap!

1. Bhargav was going to bleach his socks because they had gotten muddy the day before. As he was pouring the bleach into the washing machine, he spilled some on the floor. He got some cleaning fluid and mopped it up with a rag. Minutes later he was dead. What killed Bhargav?

2. How can you throw a ball as hard as you can and have it come back to you even if it doesn't hit anything there is nothing attached to it and no one else catches or throws it?

3.Suppose we drop a 50 kg metal ball and a 40 kg ball of silk from a height of 100 meters, which will reach the ground first?

4.When Priya was six years old she hammered a nail into her favourite tree to mark her height. Five years later at age eleven, Priya returned to see how much higher the nail was. If the tree grew by ten inches each year, how much higher would the nail be?

5.What is black when you buy it, red when you use it, and grey when you throw it away?

1.When you mix bleach and ammonia [found in most cleaning products] it creates a deadly gas that can kill.

2.Throw the ball straight up in the air.

3.In vacuum both will reach in same time, whereas in case of air density medium it will depend on the surface area which is exposed to gravity opposing force, gravity opposing force will increase as it is coming downwards and the amount of force is directly proportional to the area exposed to it.

4.The nail would be at the same height since trees grow at their tops.


6.Fm. These are the chemical elements whose atomic numbers are perfect squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
