Launching to the moon

Today I worked with Maddy and Anja on the lab called launching to the moon. At first we took a balloon and taped it to the straw on the string, we let the air out and it went straight up. We spent 734,000 and had 3,966,000 left over. Newtons 3rd law applies because when you let the air out the balloon will go the other way. I think this has to do with m2m because we will have to get to mars some way a rocket might just work.
