Head Scratchers of the Month - July

Hello again everyone! Anyone still sitting there trying to work out the answers from last month? For your sake I hope not, but be to be safe be sure to shower before you start cracking on with these ones! 

Nice easy one to start...

What has a head and a tail, but no body?

Too easy, I reckon. One more simple one and then we’ll get down to business!

What has an eye but can not see?

If you’re still stuck on the first two, its all uphill from here I’m afraid, so step back and think simple. 

A ladder hangs over the side of a ship anchored in a port. The bottom rung touches the water. The distance between rungs is 20 cm and the length of the ladder is 180 cm. The tide is rising at the rate of 15 cm each hour.

When will the water reach the seventh rung from the top?

I hope you don’t hate me too much after that last one! Here’s a riddle from the Batman villain the Riddler!

If you look at the number on my face you won’t find thirteen anyplace.

A nice tough one here to finish, read it carefully is all I will say.

Is it legal for a man in California to marry his widow’s sister? Why?

All of the answers are at the back for you, be sure to let me know how you get on and if you have a good riddle, email it to me, and we’ll try to squeeze it in!
