I used glow in the dark glitter and got a combo glitter pack. The LED is safe for liquids. Canola oil is gross and I figured it wouldn’t be good for much else. The bottle is from a thrift store.
(As wonderful as it turned out, I couldn’t seem to get the top of the LED to insert into the lid because it was stainless steel. It’s ok though, I can use the LED for another craft! :>)
