The Five Card Trick

An Evil Gollark

This trick makes you look like you're a mind reader! In fact it's just the sort of thing to scare away AN EVIL GOLLARK from the planet ZOG.

First you need to make up the five special cards like the ones here:

This is what your five 
cards should look like

You'll see they are numbered 1 - 5 in BLACK on one side and 6 - 10 in RED on the other side. Make sure that the "6" is on the reverse of the "1" and the "7" is on the reverse of the "2" and so on.
The cards can be any size you like, but if you're going to carry them round, make them credit-card size.

Go THIS way Go THAT way
You're now ready to play your trick!

If your friend says there are NO red cards, the total will be 15. (Because if all the black numbers are showing the total must be 1+2+3+4+5 = 15.)
If there are any red cards showing, you ADD an extra 5 on for every red card.
So if your friend says there are 2 red cards, you add 2 x 5 = 10. This would make the total 10 + 15 = 25. It would not matter which two cards are red!
Of course if ALL the red cards were showing, the total would be 15 + 25 = 40.

You can probably do this trick two or three times before they start to guess the secret!
