  I want to build one! You guys should do a separate build video like your normal build videos. I am still a little fuzzy on how the bottom roller and ground work.

  Now my kids are wanting me to make one.  I think all the neighborhood kids are going to come test it out.  Great project.

  two things that might improve things for you. &nbsp;The first is using either a clear, lucite (plexiglas) tube or a white (rather than black) pipe. &nbsp;The black PVC typically uses carbon as a colorant: this makes it somewhat conductive. &nbsp;The other is to use a bottom charge sprayer. &nbsp;By adding a source of energy at the bottom roller, you can actually increase your surface charge at the top. &nbsp;Finally, some of your readers might be having problems keeping the nylon belt centered on the bottom roller. &nbsp;The point that might be missed here is that the lower nylon roller must be convex which makes that roller self-centering. &nbsp;If it isn&apos;t convex, it will be difficult to keep the belt centered.<br><br>Great job. &nbsp;I hadn&apos;t thought of using a smaller bowl to act as a coupler to the larger, intact sphere. &nbsp;Very clever!<br><br>Thanks for sharing this.<br>Doug
