Don't try this at home.
The rubberband broke yesterday. It feels crumbly to the touch, like a rubberband that's been sitting in a drawer for 10 years. Just three weeks in a little hot sun and some cold weather.
Live and learn. I'll start using garden twine to hold the plastic in place.

I use punctured 700c inner tubes for bicycles. First I cut on either side of the stem (air valve) then fold the tire in half and cut it in two. I then use a square knot to fasten the tube around the bucket. Bicycle Shops just throw the inner tubes away so just ask your local shop if they could save you some.Thanks David!
