Chemistry at ASU

Today we went to ASU to see the science facilities and even use some of the items in them. First we saw an electron microscope which we learned different measurements of weight and that electrons are not coloured at all, but that it was the colour from the light. Next we saw a teacher who showed us how light can refract off certain items. For example we turned on a fan with 3 different colours on three different blades. then turned off the lights and turned on a strobe-like flashlight which at different speeds of flashing showed different things on the fan. Also, I got to ride a hovercraft which actually floated in the air! Then we went to a room with two electric shock machines where it recreated what shocking your friend when you rubbed your feet on a carpet would feel like. Afterwards we went to an air pressure room and learned that there is an outside air pressure and inside air pressure for example every time you breathe in it is exerting outside air pressure to your body. Then we went and lunch and talked to two undergraduates. Lastly, we went to an auditorium and saw a balloon filled with hydrogen explode when a flame was near it.
