What is NASA's research?
NASA has always been on the cutting edge of aviation safety research, though many of the technologies the Agency develops also find practical application in ground transportation safety. One of the most prominent examples of this type of technology transfer is the grooved pavement developed by NASA in the early 1970s. While researching runway conditions, NASA scientists discovered that cutting narrow grooves into the surface of runways allowed rainwater to flow off of the tarmac, decreasing the troubles associated with wet, slick runways, including slipping, hydroplaning, poor handling, and reduced braking times.
Is ice free safe?
Now that Ice Free is commercially available, people everywhere can experience the advantages of this NASA-derived technology. This anti -icing agent adds an extra level of safety to air travel.

The Scoop on Ice-Melting Salts
Most homeowners are painfully aware that hacking away at the ice that forms on walkways, driveways, and decks following a winter storm can be a dangerous, back-breaking chore. And they are also aware that ice poses a real hazard to passersby, causing slips and falls.
Prevention Is the Best Protection
For decades, homeowners have dutifully gone out after a storm, sprinkling copious amounts of chloride-based products around their property in hopes of easing ice removal, without knowing that these products were not particularly safe for their four-legged friends—and in cold weather, they weren’t particularly effective, either.
How It Works
Whenever you hear your local weather people announce that crews are out pretreating roads and bridges, you should be outside too. Grab your pump sprayer and apply PlaySAFE lightly on walkways just before snowfall (tip: It can be applied up to 48 hours before snowfall begins, but the fresher the better).
What if You Miss the Weather Forecast
PlaySAFE can assist as an ice melt, if the ice is thin. Just spray directly onto ice; as soon as the solution starts to penetrate, you’ll hear the ice begin to crackle. Depending on ice thickness, you may need to reapply every 15 to 20 minutes until all the ice dissolves.
If You Love Your Pets, Read the Label
Don’t pay a premium for a safety measure that doesn’t exist: A cute dog on the label is no guarantee of a pet-safe product, as pelleted products are not required to disclose their chemical composition—even when safety claims are made. Almost all are salt based, making most granular ice melts either painful to pets’ paws or toxic to their tummies.
