Upon registering the amount of enclosed liquid, this glass would display a red band where if hit at that point or higher it will probably topple. By first pushing it across the target surface via a calibration button at the bottom, the friction coefficient can be calculated to give a more exact cry line location.
Also other milk containers such as sleeping cows could be marked with a red stripe tumble margin, and judo combatants could adjust the height of their belts to reflect the push over point.-- FarmerJohn, May 12 2005 I thought this would be a helpline for use by those that had spilt milk: "It just...toppled over! Sob, blubber..." but this is also cool. [+]-- DocBrown, May 12 2005 //sleeping cows//hee hee.
that made my day!-- po, May 12 2005 Do judo combatants drink a significantly larger amount of milk?-- hidden truths, May 12 2005 applied force seems to be an overlooked degree of freedom in this idea. Bones!-- daseva, May 12 2005 That's where "probably topple" comes in since the force cannot be known ahead of time.-- FarmerJohn, May 12 2005 Okay, I'd rather knock a glass over every now and then, rather then have to do COF tests and look for lines every time I take a drink! How about... ooh, nevermind...-- daseva, May 12 2005 random, halfbakery
