As a past chairman of a Kite Club, I would suggest that getting your children interested in kite flying, would get them into the open air and enjoying the ability to control something at a distance. Kites are very different from when most of us were young, and are improving all the time. Many of us were taught to run with a Kite, this is somethingthat destabilises the Kite and causes it to crash. Hence we lose interest and give up. One piece of advice I would give, is to get your kite from a reputable Kite shop. These can be found on the WEB. Just type in Kites, and you will get a lot of information. The biggest kite at the moment is aout the size of an Olympic Swimming Pool, and fifteen School Buses can be accomodated inside it. The World record for height of Five Kites on one line is around34,000 ft and there isa large variety of kinds of kites, including (No Wind,) kites which can be flown indoors, in a Games Hall. If interested put in. Kite Makers, or Suppliers on the W,E.B and you will be surprised what comes up. Do not buy Kites from Stalls at the Beach, they are likely to be untested and will only dissapoint. Kite prices vary from about £6 to £ 7,000 if you want a world beater, Very large, Display Kite. There are hundreds of Kite Clubs in many Countries around the World, They will offer advice and guidance should you wish it. Cheers Stuart.
