I started brainwashing my daughter with star wars story books at a young age.
so obviously, i have to make her a lightsaber to play with.
for the tube, i use bubble wand like this that i got from dollar store.
if u simply put a flashlight inside, it doesn’t glow much, so i made a paper tube diffuser using printer paper and put it inside the bubble wand. i cut out a piece of paper and taped it to one end of the paper tube so that it doesn’t get too bright there.
and for the flashlight, i use this one.
it came with a cool white xpe, 5 modes driver, 0.8A on high. together with the paper tube diffuser and bubble wand, it doesn’t get too bright even on high which is perfect for kids. and protected 18650 of course. 3*aaa light is probably safer, but nothing in my collection fits the bubble wand. i duck taped the wand to the flashlight. the duck tape part doesn’t look very good, i will probably dress it up a bit later.
