You have 12 black socks and 12 white socks mixed up in a drawer. You’re up very early and it’s too dark to tell them apart. What’s the smallest number of socks you need to take out (blindly) to be sure of having a matching pair?

 

3 socks. If the first sock is black, the second one could be black, in which case you have a matching pair. If the second sock is white, the third sock will be either black and match the first sock, or white and match the second sock.

You have a fox, a chicken and a sack of grain. You must cross a river with only one of them at a time. If you leave the fox with the chicken he will eat it; if you leave the chicken with the grain he will eat it. How can you get all three across safely?

 

Take the chicken over and leave the fox and the grain. Go get the fox drop it off and pickup the chicken. Take the chicken back across and pickup the grain and leave the chicken. Drop the grain off with the fox and take the chicken over now all of them are on one side!

The Muller-Lyer illusion:

Are the coloured lines the same length?

 

They are!  The different colours and “framing” from the arrows surrounding the lines make them appear to be different sizes, but they are actually equal length.

The river was frozen.
