A Really Cool Cannon

I saw this video on YouTube, but my mom found it again here. I really wanted to make a big air cannon but soon found out that those big trash cans are not cheap. It took a bit of thinking, but I found a way to make a little air cannon. This is a picture of the one I made.

Materials List:
Rubber band
Styrofoam Cup
Plastic Sandwich Bag

Here's how I made mine:
First, take a styrofoam cup and cut a hole in the bottom that's about 1" around.
Next you might want someone to help you. Take a sandwich bag and cut off the zipping part. Have your helper hold the plastic bag over the top of the cup while you put a rubber band around it. To fire, flick the sandwich bag. Enjoy! (P.S. You can help your mother dust with it!)

Sierpinski Triangle Part 2

There is an evolutionary theory called Chaos Theory. The theory of the "Big Bang" is an example of Chaos theory (funny they're related huh?). Chaos theory is like this: they say chaos sometimes repeats part of the pattern, creating things. The Big Bang supplied chaos. A visual, repeatable example is the Sierpinski triangle. Read what this guy has to say here. I want to refute that last paragraph. He says that the 'randomness' in the triangle proves evolution. I'll tell you the chaos game.
Draw an equilateral triangle. Label the top point '1,2'. Now label the bottom left '3,4', and the bottom right '5,6'. Pick a random point anywhere in the triangle. Roll a die, if it's a 1 or a 2 , put a point halfway between the last point and the point labeled '1,2', same for the other corners. Do this 20 times (it gets boring, I know-you can also try it online here). Take a break and do 20 more until you have 400 points.( Or do like I did, and get a friend to take turns with.) Looks random at first huh? Then you see the pattern. An evolutionist would say chaos created it. But is it really chaos? It has rules set to create the pattern. If it has rules, is it chaos? I don't think so. We don't know much about the discoverer, but I do know he didn't invent the triangle. He discovered the rules that God set.

Sierpinski Part 1

I'm starting with the Sierpinski Triangle (pictured above). I'll add more details later, but for now, I'm still learning how my blog works. I'll post more about the fractal and the man that discovered it in a later post. (Hopefully not too much later!)

I'm here! Glad you came by to visit. This is a place for me to share my love of science and technology (gadgets, really). If you share this enthusiasm, I hope you enjoy my little spot on the web. I hope to add some cool links and videos to experiments and projects you can have fun with at home.
