Ready for a hardcore work out of the mind? Then enjoy solving this riddle:
You are given 9 gold coins and a scale. One of the coins weighs either less or more than the other 8 coins. By using only the scale to measure the coins 3 times, can you figure out the odd coin? And for extra special bonus points can you figure out if the odd coin is heavier or lighter?
Things you can do:
-Weigh more than two coins simultaneously
-Weigh unequal amounts of coins (3 on one side 4 on the other)
-Label or "mark" the coins
Things you CAN'T do:
-Use your hands to measure
-Add coins gradually in a single weigh

Brain Teaser
Gotta keep that brain sharp! Leave answers in the comments.
The International Enchantments Festival was held this year in Liverpool, England, and just about filled the town's finer hotels to capacity. Among the leading exhibitions were five new enchanted objects, each designed by a different person (including Prof. Kimil), each of which reputedly had a different capability. Unfortunately, each had a different type of breakdown during the demonstration of its skills. Can you discover, in order of exhibition, the names of the inventor and his or her charmed object, what each object could do, and a description of its breakdown?
1. The vase (which didn't explode) appeared sometime before the object that plays piano.
2. The object charmed to change a baby's diaper kept tipping over until the child's distraught parents called a stop to the show; this object isn't Prof. Lobiesk's creation.
3. Mr. Phantom's object (which is either the quill or the tripod) didn't appear third.
4. The object programmed to assemble Danish furniture (which didn't explode or run around in circles) appeared either first or fourth.
5. Prof. Black's object appeared sometime before the object that wouldn't move.
6. The frying pan and the object that plays piano are, in some order, the object that started to pour out smoke and the object that appeared second.
7. The tripod doesn't draw humorous caricatures.
8. The quill didn't appear just before the frying pan.
9. The object that wouldn't move wasn't programmed to assemble Danish furniture.
10. The frying pan appeared sometime before Prof. Mott's object.
11. The tripod appeared sometime after the object that prepares French cuisine.
12. Prof. Kimil's object appeared just before the boot.
