Not new, I know ...
but for those who have missed this routine.

There are various LED monte products out there ... but the results are the same.
Three small LED lights are displayed, just as the 3 shell monte.

When the small LED lights are connected to a battery, one shows colour red, and 2 show colour green.

The LED lights are moved around on the close up table.
But no matter what the spectator chooses they cannot find the "odd" coloured LED.

The answer will amaze you ... well it did me.
I had no idea that it was possible, true genius.

For a close up worker - nothing to go wrong - all self contained.
Leaving you squeaky clean.

Yup, I like it too. A nice and surprising little thing to have and perform.
