How can I make a roulette wheel?
What about a large fruit bowl and a ball bearing/marble plus a black and red magic marker pen for the wheel layout. The base of the bowl would need to be flat of course with a cup saucer turned upside down. To separate the compartments you could squeeze lines of bathroom sealant as separators. I have never attempted to make a roulette wheel so if it doesn’t work out I apologize before hand. Good luck with innovations. If you need a layout of the roulette wheel to use as a template the site below has a roulette wheel diagram.
