Hourglass

<spoiler>

After getting all the hourglasses to stop at the same time, the word GRAINS appears. Two letters in each glass.

using the clue from the video, an hour glass with @ symbols, writing a e-mail to grains@vanishingpointgame.com auto-replies the answer: candelabra</spoiler>

<spoiler> How to solve the puzzle: Start the time. When one of the hourglasses is finished and the time stops turn it and start again. If two hourglasses finih at the same time turn them both and start again. Turn ONLY the hourglasses that are finished. Repeat the process. After 20-30 moves the puzzle will be solved. :)
