Science Fair Project: What Makes the Airplane Fly? Posted By : Morton L. Barish

Mon, 29 Aug 2011 00:00:00 -0400

A good idea for a science fair project is to find out what makes an airplane fly. We earthlings are really two dimensional animals. At an early age we learn how to ride a three wheel bicycle. We learn how to turn left or to turn right. After a while we get on roller skates, and here again we learn how to turn but whether on the bike or the skates, we never learn how to go up or down. You just cannot go up or down in our two dimensional worlds, not until we learn how to defy gravity.

How to Sail a Small Boat from Europe to the Caribbean, Good Idea for a Science Fair Project Posted By : Morton L. Barish

Sun, 28 Aug 2011 00:00:00 -0400

Make your imaginary dream come true with a trans-Atlantic sailing trip to the Caribbean Sea. The best place to depart from Europe to get ready to cross the Atlantic is Gibraltar. When you entered the Mediterranean Sea you had to convert your boat from United States outfitting to suit the very different needs of the Med. For one, the 120 volt electrical system compatible with all U.S. ports just won't work in the Med. Virtually every country has different sized electrical plugs and a 220 volt electrical system is necessary. You had to install a transformer to handle this difference when you arrived into the Med, but now you have to convert back to the 120 volt U.S. electrical standards.
