Questions from KB

I have to pause and think before I answer KB's questions or pass it on to the dad when he gets home in the evening if I don't have time to google it.  I am partly writing this because it is interesting for me to read these sort of posts a couple of years later.  I plan to look up some old posts to see what KB used to be like at age four.

Anyway - some of the questions from the last two days:

1) Mamma, if I put an Apple in water and freeze it, will it get preserved for ever? (He has a piece of apple frozen in a cup of water in the freezer - he plans to keep it that way until he goes to college apparently!).

2) If gravity is such a powerful force, how am I even able to jump on my trampoline?

3) Mamma, suppose I am floating in water and gravity is everywhere, how come I am able to float?

4) What makes water turn into ice?

5) If fire comes out of the rocket when it takes off, how does the metal tube at the base of the rocket not get burnt?

6) Why do we need tissues?

7) How does the food know to go into the food pipe and not into the wind pipe all the time?

8) Will the sun also die and have a new sun be born later after billions of years?

9) Mamma, sometimes when I brush, there is a bubble on my lips, how come it doesn't burst when I touch it with the brush?

10) How is sand formed on earth?

11) Why does the earth spin around the sun?

12) Mamma, if the doctor cuts open the mom's tummy to take the baby out (I have not told him how natural delivery happens because he will then think too much about all that - I felt it can wait), then what do animals in the wild do? They don't have any vets to take their babies out right?

13) Why does old paper turn yellow?

14) Today's question when we were driving back from Target shop while listening to his favorite CD: "Mamma, how do they put the music on the CD if people are not singing in front of it?"
