Paperclip Overboard
This is a cool expiriment which shows that water can be like you! Try it!
Ingridients:Bowl,2paperclips,few pieces of tissue paper,pencil
1.Fill the bowl with water
2. Try to make a paperclip float. It doesnt float. Right?
3.Now then,get the second paperclip out. If you use the first one. It will sink anyways because it is already watery.
4.dont put the paperclip into the bowl yet. place a piece of tissue paper about the size of 2cm wide and long. And place it into the water.
5.QUCKLY! put the peperclip on the tissue paper!
6.now wait for 5 seconds until the tissue paper sinks a bit, now push the tissue paper below making sure the pencil and the tissue paper don't touch the paperclip.
It will float!
-This happens because of water tension
- It is like a layer of skin madeby water moelcules.
-The tissue paper help it group together to make a wall that stops the paperclip from sinking
-To make your water even stronger, add a few dabs of baby powder

Carbon Dioxide
I love working with acids and baking soda, its just fun to watch the bubbly mixture froth up. That stuff is called Carbon Dioxide. I remenber when I put white vinagar, lemon juice, kool-aid, watery salsa, balsamic vinagar and red wine vinagar into sepret bottles. One by one, I put little pakets of baking soda in the bottle,put the cork on, shook it up, and then timed it. White Vinagar was the fastest followed 1 second close to lemon juice and watery salsa and kool- aid didn't produce Carbon Dioxide. If you want to try this, I suggest doing it in the bathroom, it's a messy experiment!

The clean penny!!!
Once, there was a penny made in 1950!!! A class put water, vinegar, and sugar into a container. They stuck the penny in the substance for 20 seconds. When they took the penny out, it was clean!!! But how? When the water, vinegar, and sugar were mixed, it created a chemical that was able to clean the penny. It is very fun!! You try it!!!

The booming valcano
In school we were learning about valcano and once our teacher told us to do one! We had to pick parnters and I picked my best friend, Ashley. Two days after we were assined to do our project we went to a store to get our supplies. We got styerfoam, twigs,clay,vinger,red dy, and soap. First,we shaped the clay into a valcano. Then we waited a day for the clay to get hardened. Next, we put the twigs arond it. After, we did that we put a ementy bottle inside the valcano and put the red dy inside the bottle. Finally, we were done and it was the day to share our projects. When it was our turn to share our project we were so excited. We were ready to put our vinger and soap in. We slowly poured it in and then everything exploded. It was awesome!!!!!!
