Yesterday

This is what happened yesterday. Car broke down today.

Went to the NUS Physics to Excite. 

First we made a small contraption which uses rubber bands as the source of energy. When you push it, it is supposed to roll forward, then backward, and so on. 

The room was full of rolling Mickey Mouse Clubhouse tins with colourful lids. (There were two rubber bands stretched between the lids inside, with a bolt to act as a balance.)

I tried to dodge rolling tins, which were everywhere. The instructors (?) there were helping people to glue the lids on to the tins with glue guns. Excess glue could be trimmed off with a pair of scissors. I used a penknife in my pencilcase and somebody was very suspicious ("I wonder why she carries a penknife in her pencilcase"). But that person used the penknife in the end. 

We then made a motor with a AA battery with a wire soldered to the positive end, a magnet and a screw. It's easy to set up. (google: Maxwell's Motor) Once set up, you touch the exposed bit of the wire to the side of the magnet and off it goes! You know the motor's fast enough when you smell smoke. Or see sparks, although I don't think that's really good.

Next: tea break. Three doughnut-ish things with two swiss rolls. 

After that, 6Q and half of R went to the DemoLab, which is very very great. We moved from exhibit to exhibit and I won't elaborate. I like the one where you rub a wet finger around the edge of a wineglass. Water provided murky, of dubious origin. Then there was a sticky black thing which was being thrown around. Apparently it looks like a badger.

Lots of stuff were in that Lab: tuning forks, machines that illustrated centrifugal force, etc, etc. 

At one corner was two NUS books 'pasted' together. It's a bit hard to explain, but something like the pages were overlapping- refer to piccy. The instructor couldn't seperate the two even if he hung on for dear life. Well Aaheli could.

Other than that... yeah.
