I'm guessing the answer is heck no, since the remains are now fossilized but I'll ask it anyway.

ADDIS ABABA (Reuters) - Ethiopian scientists unveiled on Wednesday a 3.3 million-year-old fossil of a girl, which they believe is the most complete skeleton ever found.

The fossil including an entire skull, torso, shoulder blade and various limbs was discovered at Dikaka, some 400 kms northeast of the capital Addis Ababa near the Awash river in the Rift Valley.

"The finding is the most complete hominid skeleton ever found in the world," Zeresenay Alemseged, head of the Paleoanthropological Research Team, told a news conference.

During spring break, there was a club that had CO2 tanks that shot blasts of CO2 on the crowd for a cool blast. I was thinking getting a tank and hooking PVC tubing to the tank. The open end of the tube would hang over the crowd. How practical is this? Does the CO2 loose its effect while traveling through the tube? Any suggestions on how to make this work? Thanks.

As they say, everything that has a beginning has an end.
Well we know the beginning of universe, it began with a big bang.

How is it going to end? Is there any scientific anomaly which might bring the end closer than we think?

I'm having problems with the one physics problem. Not sure which equation(s) to use. Anyways, here is the problem:
An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at +43 ft/s2. After some time t1, the rocket engine is shut down and the sled moves with constant velocity v for a time t2. Assume the total distance traveled by the sled is 15950 ft and the total time is 90 s.

I need to find t1, t2, and the velocity.

If you have a lion and a christian in an enclosed, circular ring (like in a Roman amphitheatre), and they both have exactly the same maximum speed, instant acceleration, are both intellegent and have perfect reactions, can the Lion catch the Christian in a finite amount of time?
