Every tuesday 2 of the classes in our school go to something called Mahi tahi and yesterday we had to make waterbottle car that could move atleast 1 metre without touching  it in any way you could only use 3 rubber bands 1 baloon a couple of these weird popsicle sticks some other stuff that i cant remember . First me and my team was not going to well so we took a while and we ended up with something that looked magnificent we had  Sellotape all around a balloon on top and the nozzle had a rubber band around it when it was our turn to see if it can go 1 metre when we got the rubber band off we were amazed at how far it can go it went 1 millimetre got to be 1st
