SUMMARY

To enhance the spinning speed of a bucket, utilizing a longer rope is essential as it allows for prolonged spinning, facilitating the formation of a paraboloid shape. Additionally, opting for a larger bucket can reduce the required spin speed while still achieving a significant concave. The discussion also suggests that tying the bucket handle with a single knot may not be the most effective method, and exploring alternative tying techniques could yield better results. Lastly, using an old record player turntable set to 78rpm can serve as a practical tool for achieving faster spins.

Is there a better way to tie the bucket than single knot on the handle? Or type of rope to use...that would increase speed of the spin? Mine just don't spin that fast at all.. Plastic bucket.. The concave is quite small compared to some I've seen done before.. Any better way to set it up?

Is it spinning long enough for the friction to get the water turning? You could try a bigger bucket. It won't need to spin as fast to get a big concave.
 
A very long rope will allow spinning to continue for longer - to allow the paraboloid shape to form and for other small perturbations to die out.

An old record player turntable, set to 78rpm is good - if you can find one.
