  1. The blue arrow is where the water comes rushing out because of the air. The red arrow is where the water and cold water meet each other and go speeding high. lastly the green arrow is pointing to where the air is pumped into. That photo on the side is a photo of Saturn 5. It was really challenging to make them work. We needed to pump up the bottle to make it go to the stars (sarcasm). Then the other person had to pull the pin and then it went of. when it came back down the inside had steam coming out. Thanks bye.

  2. Hi John, I like how you showed me what the different arrows do and what happens to them it reminds me when room 3 and room 4 did it. maybe you can add what the arrows do on the post.
