Mr. Olson took all of his chemistry students, including me, to Mills Creek Canyon. My fellow classmates and I walked about 3 miles to the Canyon and all around it. It was beautiful, I climbed picnic rock and expolred the creek. It is cool to know that nature is hidden right in our backyard.

Bending Glass
I was taught by Valerie Yermakova(the blonde girl in picture) on how to bend glass. I formed many cool shapes with the glass.
Steps:
1. Put on Safety Goggles
2. Get glass
3. Turn of the lighter than the gas and light the burner
4. Put part of glass that you want to bend in flame
5. When hot it enough the glass will start to bend
Science:
When glass is put into the flame, the glass part in the flame becomes malleble. (Bendable or mendable)

IProposeWe Make Handheld Fireballs
IProposeWe Make Handheld Fireballs
Materials:
- 2" x 5" strip of cotton cloth (like from a t-shirt)
- 100% cotton thread
- needle
- naphtha lighter fluid (ex: Ronsonol™ or Zippo™)
- match or lighter
Procedure:
- Thread the needle with cotton thread.
- Tightly roll the cotton strip into a ball.
- Pierce the ball with the needle and wrap the ball with the thread. End by running the needle through the ball one more time and break off the thread. And tie a not at end of thread.
- Soak the ball with lighter fluid. Don't soak your hands.
- Don't ignite the the fireball while you are holding it. Set the ball on a fire-proof surface. For example, a frying pan.
- If you want to hold the fireball, you should pick it up with tongs and carefully/slowly set it on your hand. That way you'll be able to tell if you can take the heat or not. If you believe you can hold it, pick the fireball up using your fingers.
Safety precautions:
No loose clothing!
It's fire be responsible!
Don't soak hands with fluid, if hands get soaked wash immediately
It's best to use 100% cotton fabric and thread. If the fiber is synthetic (like nylon or polyester) it might burn or melt, with unpleasant consequences
The fireballs are reusable. Put them out when they run out of fuel or else the cotton will burn (you can tell this is happening when the ball starts to blacken and produce sooty smoke). If you get to the point where the cotton itself is burning, the fireball will be too hot to hold. Ideally you want to extinguish the fireball before it consumes all of its fuel. Simply soak it in more lighter fluid and relight it to reuse it.
Scientific Principles:
Fire is capable of being touched and not being burned using a special lighter fluid (naphtha).

St. Francis
I was invited to St. Francis for a meet. I did really bad I think. I got 4th place in both and I wish I would do better. I was so frustrated. The top 3 got shirts with placing and I was just one place away from getting it. I guess I just have to do better and hope that centripital force helps me with discus. I pr.ed in discus. Which means I beat my record, so I need to keep doing that.
Meet at Newark
Some Mills Throwers were invited to a meet at Newark. Throwing has to due with science for ex centripital force. I am on JV an d was invited. I came in second for shot put and another Mills girl got 1st in both discus and shot put. Her name was Sabrina Mendoza. I got 4th in discus. I did bad. We both got medals for getting in the top three.

The day before CSM meet was Formal. It was so much fun. My aunt made my dress it was purple. During the dance they had good cookies and they had good songs. It was crazy. Once in the dance I sucked a helium ballon at 9 pm and all night till I went to bed I had the helium voice. You know the high squeaky one. I was so scared and didn't know what to do. Everyone thought I was faking. The next day I woke up at with no voice.
