80 pounds of Silly Putty + 10-story drop = giant splat

Students at NC State are always looking for ways to push the envelope of scientific inquiry, to take their research to new levels and find creative ways to answer important questions.

So why sillyputty1not drop an 80-pound ball of Silly Putty off the roof of D.H. Hill Library?

That’s what a group of high school students attending an engineering camp at NC State plans to do on Tuesday. They are dropping the large ball of Silly Putty 10 stories onto the Brickyard so that they, as the official press release says, can “see how materials react under pressure.”

What the press release doesn’t say is that it will just be plain fun to watch a huge blob of Silly Putty explode when it makes contact with the Brickyard. If you want to see for yourself, be at the Brickyard by 2:45 pm on Tuesday. That’s when they are planning to drop the Silly Putty.

University officials say the 80-pound ball will be the largest ever dropped from the roof of the library. Students attending the same camp in past years have dropped 50-pound balls of Silly Putty. They shattered on impact.

The Materials Camp is a weeklong summer outreach program for rising high school juniors and seniors  hosted by the Department of Materials Science and Engineering in the College of Engineering.

    If they are engineering then they need t determine the optimum poundage for a given bounce or shatter. This is why graduated your business school.
    Have fun.

    Where can I park on campus so I can come by and see this?!

    You can get a visitor parking pass or park along Hillsborough Street.
