Friday 25th August 2006 Issue: 51

We’re going Haywire over the August Bank Holiday weekend! Print off a copy to keep you occupied in the traffic jams.  Or whilst waiting for the rain to stop… No! Don’t think that way – think sunny thoughts. So what have we got lined up for you?  Read on and find out.

  1. The Buzz – 55,000 firework rockets and healthy gum
  2. Crash Bang! – Make a straw rocket
  3. Up for Grabs – Family pass for Hands On
  4. Winners – Eureka! It’s Robogeddon
  5. Tummy Ticklers – get sniggering!

1. The Buzz – Science news delivered to your inbox…

If you were in or around Plymouth last Wednesday night you might have noticed a bit (!) of commotion. Some 55,000 firework rockets lit up the night skies in a noisy world record attempt. The monster bang was set up by Dr Roy Lowry from the University of Plymouth to mark the 10th anniversary of the British Firework Championships.

To get the record, all the bangers had to go off in five seconds. Experts are now checking film of the event to decide if the record has been broken. The current record is 39,210 rockets set off by Terry McDonald in the Channel Island of Jersey in 1997.

For more details check out the BBC Newsround site

Have you read Charlie and the Chocolate Factory? Remember Violet Beauregarde?  She should have been called Violet No-regard (for her teeth, that is).  All that chewing and gnashing on gum. What a disgusting habit. Scientists have come up with a gum that contains bacteria that are good for your gnashers. The good bugs in the gum stop the germs that cause tooth decay from sticking to and attacking your pearly whites. Other products, like toothpastes and mouthwashes, containing the bacteria, which is called Lactobacillus anti-caries, are going to be marketed. The bug could also be put in deodorants to beat body odour. Stinky armpits are often caused by bacteria, and the clever Lactobacillus beats that bug too.

To find out how to look after your teeth

The new chewing gum should be out in shops in 2007. But chewing the gum doesn't mean you can skip brushing your teeth. Dentists say the best way to look after your mouth is to brush regularly, use fluoride to strengthen your teeth and avoid sugary foods. Plus you know what happened to Violet Beauregarde don’t you?  Don’t mention blueberry pie…

2. Crash Bang! – Exciting experiments for you to try at home…

Make a straw rocket

You will need:

  • Pencil
  • Pattern
  • Paper
  • Sticky tape
  • Scissors
  • Drinking straw

What to do:

  1. Cut the paper strip and the fins from the pattern
  2. Roll the paper strip around the pencil.
  3. Tape the tube in three places.
  4. Take out the pencil.
  5. Cut off the ends of the tube to straighten it.
  6. Tape fins to the tube.
  7. Fold over the upper end of the tube and tape it shut.
  8. Insert the straw most of the way.
  9. Blow through the straw to launch it. 3,2,1 Lift Off!

What’s going on?

The end of the rocket tube is taped shut.  So when we blow into the straw the air cannot escape and provides an upward force.  The tube fits loosely around the straw so it moves quickly upwards.  If the tube were a tighter fit then there would be greater friction between the tube and the straw.  This would act in the opposite direction to the upwards force and the rocket would not launch so far.  Can you think of any ways to reduce the friction between the straw and the tube?
