Combustion
Hypothesis: I think a small blue flame the size of your thumb will shoot out the top of the bottle. I Then think you will see a small portion of soot around the rim and laying next to the bottle but not much.
What really happened: A huge flame came out the top and the rocket shot straight across the room in a huge blue flame.
The site we read was about how combustion effects the world and what chemicals are interacted with it, such as H2O.
CO2 gas
Hypothesis: I think that the CO2 will cause a small explosion type thing simalar to the last demo and might cause a small flame to appear at the top.
What really happened: The CO2 gases caused the flame to be put out because the flame needs oxegon to live.
Hydrogen Gas
Hypothesis: I think the flame will be constant for about 10 seconds then it will go out as the gas expands.
What really happened: The beaker let off a big smoke and when the flame was intereacted with it the flame made a loud pop and the gas sizzled and popped while on fire for about 20 sec till the gas
Air pressure
Hypothesis: I think the can will be squished as if a person is smashing it between there hands and the vapor will come shooting out the top.
What really happened: E first time with can facing up nothing happened. The second time with the can facing down the can sucked itself in and it need up smashed.
