In the class demonstration the water didn't come out till there was a certain amount. It came out fast at once till the end. The water went in the bigger hole.
I think there is a tube that holds the water until it is full then it comes out. Or it is the air that is in the tube. That pressurizes it until it is all gone.
The skills scientist use are predicting, observing, classifying, inferring, and making models. Predicting is when you guess about the future and what happens. You must use all of these to be a good scientist. Inferring is when you see if your prediction was right and right info you got wrong. Observing is after predicting and it is when you see what happens. Then you can classify if you where right or wrong. I had to use these when I didn't know what was in the enigma box. So i went through the process.
What happened in the expiration was there is a tube inside it. it was pressurized and then until the water got to the top it all came down and pressure made it keep going. So really it was not the tube i was talking about. But it was a different tube that you would use for other things like a hose.
