Wow Isnt The Rainbow The Best

i have a little story first
"i was working at a hotel some time ago and a guy comes in,
he asks me for a room and i tell him he has no reservation,
he looks at my tie and tells me no tie said i have a reservation here,"

so i have a conspiracy is it true that in the future we are going to have better flashlights then even the fleshlight?(jk!)
i used to be a big fan of home do-it-yourself videos so i never needed one but thats ok for eternity

reason why i ask is from my work i see led being used in card readers including credit cards but is it safe
would infared be better do you think

 

What?
