You will need:
- yogurt tub or an type of curved plastic tub
- tin can
- threaded rod approx 6mm (1/4")
- bolts for threaded rod
Step 1: Cut the parts
The sides of the yogurt pot forms the petals, so cut away the top and bottom parts of the pot and then cut strips out of the sides. I made a lotus flower, with 8 petals, which curve low. So each pair of petals is made from half the circumference of the pot. The pictures will give you a good idea of what I'm talking about.
You could make any sort of flower, for example a rose or tulip - you might want to use more curvature of the pot so each pair of petals takes us say 3/4 of the circumference. It also depends on how the plastic retains its shape.
Step 2: Drill everything
then drill drainage holes in the base of the tin.
