BoTtLe RoCkEtS

for the past week and a bit our science class has been working on bottle rockets which we launched today. we used an l&p bottle which we painted golden yellow and pink. on our fins we had a  blue one as well as a red one and a yellow one before most of it also got painted yellow gold. then we had to make a cone using newspaper it took us a while to perfect the tip but we got it in the end.

to fly it we used a air pressure thing connected to a wooden something connected to another thing that connected to our rockets. we had to push down on the air pressure a couple of times to get it to go then the water splatted out to let it fly up.

our group worked well together to get everything done and i really liked to make this bottle rocket and collaborate with my friends.  

After that we cut the cone and the fins off using a craft knife and then we cut the bottle in half. After that what we did is we filled the bottom half of the bottle with water and then the top half  we flipped it upside down we put felt through the neck of the bottle and fed it through up to the top to absorb water. Then we filled the top of the bottle with stones and pebbles and dirt up to about 3/4 full then we put the seeds in and then filled it the rest of the way with dirt.  


Our planters have been going for a week and they have grown a bit and you can now see the green plants on top.

UPDATE:
there isn't any growth in the plant apart from the leaves getting larger and taller.
