Step 5: Plug the ends of the wand (and fill it)
NOTE if you want your wand to be stiff and very robust, then instead of using the tighter rolled up paper core, you can fill it with epoxy resin. Epoxy resin is that sort of glue that you use by mixing up two parts. It can be very runny when mixed up, so you will need to plug the smaller end. After plugging the little end, but before plugging the big end, fill the wand with quick setting, two part epoxy resin. Use the 5 minute setting version rather than the really fast 90 second version and carefully dribble the glue down the inside of the wand, making sure not to get it on the outside. Don't worry If you do get a little bit on the outside though, just wipe it off carefully and quickly, you'll be painting over that later.
