New riddle
 
You have won first prize in the Pirate's Den contest. You get to choose one of twenty bags of gold coins, each bag has well more than one hundred one ounce coins. Nineteen bags have fake coins that weigh 1/10th ounce less than the real ones. You also have a scale so you can weigh them except it's one of those bus station scales that works only when you insert a penny and you only have one penny. When the weight on the scale changes the window closes on the scale.

People like Oldog are way to fast so please just let us know when you have it
and bring your answer on Tues.:hide:

and each fake bag also has real coins that weigh the full ounce?

Never mind: I would have never come up with the method for finding the good bag.

It's just like answers in the back of the book. Really successful people cheat without getting cought.

See, really smart people don't have to know the answer, they just have to know how to find the answer...;)

Here's one I couldn't get.

A piece of ice drops into a lake that is at 0C such that 0.5% of the ice melts due to the impact.
How far did the piece fall?

Ans: IIRC, 177 meters.

I'm a pirate, more people watching only helps with my sea cred.
