Well the Easter hols are upon us and Wired Up is on the case.  Whilst you’re busy watching out for the Easter Bunny and his stash of choccy eggs then see what’s happening in the undergrowth.  You may have noticed a few of our little spotted pals, the ladybirds, creeping about.  If so, Springwatch would like to hear from you. Plus find a willing adult to help you with this week’s Try This! You won’t believe your eyes. So put that choccy wrapper down and let’s get on with it!

  1. The Wire – the Science of James Bond
  2. You What?  – The Curse of the Were-rabbit?  Or Bun on the Run?
  3. Try This! – Behold the silver egg!
  4. Make a Date – Keep your eyes peeled. The Easter Bunny’s not the only thing we should watch out for…
  5. Gear for Grabs – Grow Giant Plants
1. The Wire  – Science news straight to your Inbox…

The name is bond – ionic bond.  How do you like your electrons Mr Bond? Taken, not shared…

It seems that Britain’s secret service is getting a gadget centre like the one used by super spy James Bond. In the Bond films, 007 gets a string of amazing tools from a team of expert inventors led by the character, Q. The Ministry Of Defence has brought together the best scientists in the business to develop technology to help in the fight against terrorism. The Counter-Terrorism Science and Technology Centre will make stuff to defuse bombs and sniff out explosives. A team of 15 scientists will work on various projects at a top-secret laboratory in Wiltshire.

The James Bond films have shown the super spy using briefcases, cars and watches containing hi-tech gadgets, in his fight against the villains.

If you can think up an amazing gadget for James Bond then let us know by sending us an email with your name, age and address to: wired-up.news@nesta.org.uk with ‘BOND’S GADGETS!’ as the subject. We will print your ideas and who knows… Q might be watching!

Talking of gadgets and cracking contraptions, that leads us nicely to the subject of Wallace and Gromit, or more importantly – The Curse of the Were-rabbit…

2. You What? - Science facts that might make you go “Hmm?”

Allotment holders are hopping mad as their green goodies are being destroyed by what seems to be a giant rabbit. They've called in trained marksmen after rows of veggies have been ripped up on the patches in Northumberland. But the RSPCA has called for a kinder solution, urging them to trap it in a cage and release it elsewhere. The main clues to the culprit are some oversized paw prints and sightings of a cross between a hare and a rabbit with one ear larger than the other.  What do you get if you cross a rabbit with a naughty hare?  A bad habbit.

But is there such a thing as a giant bunny? ‘Yes’ says the owner of Herman the gigantic rabbit. The mighty bunny weighs a massive 7.7kg, and his ears are a lengthy 21cm - almost as long as most pet rabbits are tall. And he is almost 1m tall. The German Giant is even big for his breed, which usually tips the scales at around 6kg.  Herman lives in a specially built solid oak hutch and chomps his way through just over 2kg of food a day. His owner says his favourite snack is lettuce. You don’t say?

The giant bunny, who lives in Berlin with owner Hans Wagner, also takes a vitamin supplement to keep him healthy, and munches through a bale of hay a week.  Herman could be the world's biggest rabbit, but Guinness World Records have stopped accepting entries because of fears people were over-feeding their pets. German Giants do not exist in the wild, and have been developed by breeders. They can live for as long as 12 years.  So Easter Bunny – beware! You have competition.  Perhaps Herman the German Giant doesn’t have quite the same ring to it though…

3. Try This! – Science experiments for you to try at home..

Now it is not usually in our nature to give you a Try This! that you can’t actually try yourselves. But we hope you’ll forgive us this time since it is a very good trick but it must only be attempted by adults. This is because it does involve holding an egg in a flame and it can be extremely tricky at the best of times. Prepare to be amazed at ….The Silver Egg!

You will need:

A willing adult

Egg preferably white or pale brown

  • Candle
  • Matches
  • Bowl
  • Water

What to do:

  1. Make sure the egg is absolutely dry.
  2. Ask an adult to carry out the rest of the investigation whilst you watch. (Sorry!)
  3. Light the candle.
  4. Hold the egg between the thumb and forefinger and place it in the sooty part of the candle flame for a few seconds.
  5. Rotate the egg so that it has a coating of soot.
  6. Pour enough water into the bowl such that the egg will be completely submerged.
  7. Place the egg in the bowl of water gently.
  8. Instead of appearing black it has a silver, mirror-like appearance! View it from different angles.

What’s going on?

Soot consists of carbon which repels water and holds a fine film of air bubbles that causes the egg to look silver when viewed through the water.

A considerable amount of the light travelling through the water is totally internally reflected when it encounters an air layer that adheres to the soot. Since most of the light is reflected, the egg appears to have a silvery, shiny surface.

The egg will appear silvery until the air dissolves into the water, which only takes a couple of minutes.

4. Make a Date – Things to see and do…

Have you noticed all the ladybirds appearing lately?  If you’ve time to spare then have a quick count of the spots. Hah! We thought as much! Seven spots eh?  Intereresting, veeerrry interesting. Ladybirds emerge from hibernation from February onwards, sometimes earlier in the south. They mate in May and June and the females lay tiny yellow-green eggs in groups of up to 50, often on the underside of leaves. One female may lay more than 2,000 in her lifetime if she has enough to eat.

Ladybirds are an asset to any garden because just one can consume more than 5,000 aphids in its lifetime. Besides greenfly and whitefly, they also prey on scale insects, mealybugs and other garden insect pests. The aphid/ladybird relationship is of great interest to scientists and was even studied in a zero gravity environment on a NASA space shuttle in 1999. Houston we have a problem.  The ladybird has flown away home, we repeat, the ladybird has flown away home…

The ladybird's bright colours warn predators such as ants and birds that it's not good to eat. When disturbed or handled it secretes oily, foul-smelling yellow fluid from its legs as a further warning so it's best to leave ladybirds on plants where they belong.

If you want to know more about ladybirds then look at the Springwatch website

You could even take part in the project by logging where you saw the ladybirds.

5. Gear for Grabs – You’ve got to be in it to win it...

How many different flow—e---er—ers gro-ow in an English country ga-ar-den? La! La! La! La! Some that I kno-ow ..la! la!….

Yes Spring is most definitely on its way so we have for you a ‘Grow Giant Plants’ Discovery Tube which contains two plants to grow and monitor over the spring and summer months. So if you fancy yourself as a bit of a greenfingers then email us with your name, age and address to: wired-up.news@nesta.org.uk with ‘GROW UP!’ as the subject. The winner will be picked at random at 5pm, on Thursday 27th April.

Good luck!
