Think Like a Scientist ! (How Can You Be Bored? Go Build Something !)

Hovercrafts are vehicles that ride on a cushion of air.  No, these are not boats, not aircraft or helicopters, they ride just above the ground or water going where other vehicles cannot and in many cases they are able to travel at high speeds. 

So how does a hovercraft work?  Fans force air under the vehicle creating a high pressure pocket of air that "floats" the vehicle.  A specially designed "skirt" retains most of the air - allowing it to seep out a bit at a time.  Meanwhile, the fan continues to force air under the vehicle maintaining the air cushion.

The propellers you see on top of these boats are additional fans which propel the hovercraft forward.

Want to make your own hovercraft?  It's easier than you think - in fact, with a few items from home, you'll be able to fabricate your own device that rides on a cushion of air.  Checkout this YouTube video for instructions!! How to Make Hovercraft at Home

GW Long students - want to receive a prize on the first day of class?  Bring your assembled toy hovercraft and a one page report about scientists who pioneered and improved hovercraft.  Include at least one photo of a modern day hovercraft that you like.

Enjoy the 4th of July with your families - Happy Independence Day !

Honey, Have you Met the New Neighbors?

My husband noticed that some new residents had moved in to our birdhouse – and they don’t look anything like bluebirds.   In fact, he was about ten feet away and one of these bees flew straight toward him and stung him on the face without warning - Ouch!!

In the summer weather it’s easy to come into contact with stinging bees or wasps that make their homes in the ground or in cavities such as a birdhouse.  Some can be very aggressive.  While it’s important to be careful, it’s more important to know what to do in the event of a sting.  Don’t assume that a sting will just be a minor irriation; for some it can be life threatening.  Check out this website Bee Sting Treatment to learn what to do in the event of a sting….. and be sure to watch out for those new neighbors!
