Step 3Prep the Tube.
make a mark on the tube where the switch is. This will be where you drill the hole for the button.
Get the button and make sure it fits the hole wen u drill it.. Not too tight and not so it will fall out.
while the guts are in (remove them to drill clearly), measure a piece if tracing paper to fit in the tube. Make sure it fits neatly with no gaps, but don't let it go over the button.
Also cut out a peace of tape or tracing paper to cap the end later.
slip the tracing paper into the tube (this diffuses the light ya know), where it ends inside the tube is where the black tape must overlap.
cover the bottom part in black tape and cut a hole for the button. leave the end open.
