Recycled Plastic Bottles as Hanging Flower Pots

[KMO Studio]

These hanging flower pots look really unique and I like the different colors used in the video.

I like that! I wonder how easy it would be to cut the small strips. Definitely would need to use a 2 liter or bigger bottle to make it easier to handle.
What do people think the age range would be in making this? Good for kids? Older people with arthritis?
