Movie projector.  This was my attempt at taking a picture of the movie projector at Ward Theaters.  The projector is kept behind a glass.  It then projects the image onto the large screen.  The distance from the projector to the screen must be exactly  at the correct focal length or the image will be blurry.  The projector produces a real image, which is why you need the glass in front of the projector.  This glass is a converging lens, that flips the image again, so it it is right side up.

VUVU

This year I was very busy during the fair.  However not busy with work, but busy with buying Vuvuzellas!.  I somehow got three vuvuzellas at the fair this year.  While most of the people play one long and somewhat annoying note on the vuvu, I learned how to create different frequencies and notes, by changing the length of the vuvu.  As you shorten the vuvu the pitch goes up, and as you extend the vuvu the pitch drops.  This change in frequency and pitch allow you to create different notes and simple songs.

Tiny Wings

Tiny wings is a very addicting game. The object is to assist ur tiny bird, with “tiny wings”, in soaring over hill and dale. The to obtain a high score you must fly from island to island, wit each island increasing in difficulty. The first island has low amplitude waves, with even wavelengths making it easy to judge the timing for descent. If you timing is perfect and ur bird gracefully caresses the downward slope of the wave you get bonus points and a nice extra boost. As you move from island to island the amplitude and frequency of the waves increase making it harder to get “perfect jumps”.

Transformer!!!!!!!

I have always wondered how my home in mililani gets it electricity. There are no tall electric poles, and no loud buzzing sounds. But after physics and a long walk with my dog kea I found the answer. A transformer!!! Hidding in the bushes. This transformer takes te high voltage and decrease it into bite size portions that can be used in homes

That’s Amazing Current!!!

The fluorescent lights have a gas discharge that uses electricity to excite mercury vapor.  They can produce electrical power into visible light more efficiently than incandescent light bulbs. There is amazing physics at work every time you turn on a light. 

Wow!! Look at those beautiful fluorescent lights!!
