I liked in. Stem week that we made a irrigation system.So what we needed to do is that we needed a pin and we put holes in the bottle. Then we had to cut the bottle in half and then we had to go out side and dig a hole in the ground. We poured some water in the bottle to let the plants all grow strong
I liked it when I made cotton candy and I was so happy when I did the irrigation system it went down quickly.
