Huge Balloons! Macy's Thanksgiving day Parade (14 photo)
On Thursday, millions of people will tune in via live streams, television or in person to Macy's 2012 Thanksgiving Day Parade for its 86th annual celebration. Thousands will flood the streets of New York City to see the parade with its marching bands, performers, celebrities, giant helium balloons and ornate floats.
The 86th annual parade is a yearly extravaganza of floats taking place in New York City. The parade will begin at 9 a.m. EST and continue until it reaches the end of its route at Macy's in Herald Square around 12 p.m. EST.
The three-hour, 80-plus-year tradition starts at 9 a.m. and boasts 16 gigantic balloons. If you are ambitious and want to brave the cold on the night before, you can watch those balloons get inflated. In addition to seeing Kermit the Frog or Spider-Man, you’ll also witness the squandering of the global supply of helium.
At projected rates of consumption, all the currently available helium on Earth will be depleted in about 40 years. While its best-known use may be filling balloons and making people who inhale it squeak like Mickey Mouse, the element’s scientific uses are arguably more valuable. No other gas is as light without being combustible.
It's not like we are going to run out or anything.
....wait, I think we are!

without liquefied helium we wouldn’t be able to make superconducting magnets like those in MRIs.
But these balloons are so cool to look at! and this is soooo much fun!
The helium we use today is found in underground gas pockets, often associated with natural gas. Helium is abundant in the universe, but here on Earth it is more elusive...
it is the by product of the half life in radioactive elements deep underground.
The rate at which it is produced accounts for less than one-half of global demand, and most of it cannot be recovered efficiently.
Don't worry about helium ending at some point in the next 40 years. Sit back, eat some turkey, watch some football, and watch the parade.
