What you need:
- half gallon milk or juice carton
- 7 bendy straws
- 2 large plastic bags or other clear plastic sheets
- tape (we used packaging tape)
- 2 pennies
We used straws and plastic bags that had been used before and washed. This was a nice project to recycle straws that we didn't want to drink out of anymore, but we wanted to use again.
First we cut the carton in half.
Then taped it closed to make a rectangular box. This will be the base of the greenhouse.
You could cover the outside with paper and decorate it at this point.
Don't worry if it isn't perfectly straight or if some of the tape shows.
