Wacky or Wise？ My dad and I found a great web site that describes wacky（古怪的） inventions.Some of them impressed us，but others made us ask，"What was that inventor thinking？"
   One of Dad's favourite inventions was the alarm fork.It's supposed to help people eat more slowly.The alarm fork looks like a regular fork except it has two lights on the handle that work like a traffic signal.When the fork's green light is lit，you can take a bite of your food.When the red light flashes，you stop eating and wait.That would drive me crazy!
   Another invention was a pair of eyeglasses without earpieces.They looked ridiculous!To wear them，you first glue a magnet onto each side of your head near your eyes.The frame for the glasses has two ends with metal pieces that the magnets attract.But I wonder what happens when you take off your glasses.Will your head stick to the fridge？
   There's also a travelling washing machine that washes clothes while you drive.Dad and I think the machine is a good idea，but it seems like too much trouble to use.First，you have to lift your car so you can fasten the machine onto one of the car's wheels.Then you add water，soap，and clothes and hit the road.But you can't drive over 25 miles an hour（40km per hour），or the machine will break.And you have to stop twice.First，you need to replace the dirty water with clean water for rinsing.And then you have to empty the rinse water so the clothes can spin dry.Washing clothes with rocks in a creek（小溪） seems easier to me!
