Today I want to tell everyone about that I made a very good invention, but this invention is the type that doesn't make our life easier.
If you wanna make it, you can use a bottle after you finish a box of milk, and cut it, then you can take some straws, so you can make the bottom.
After all, you can stick it together, but make sure you block the hole of the straw, so the water won't go inside the straw.
Then you can put some plastic things around the straw, so if the boat hits the shore, nothing would happen, and the boat won't crash.
I think this invention is not very good, because it can't make our life better, but it can carry things on the water, so can make life a little easier.
