can you use wd-40 to lube bearings?

Lol
pssst, hairspray works way better

Disclaimer: Do NOT try this at home!!! It is super easy to mess up and start everything(Including your perfect CLYW boxes and set of custom FHZs and any other plastic yoyos) on fire. Plus not only is it a terrible idea but your mother would never trust you with fire again.
So in short DO NOT DO THIS!!! EVER!!!
