Your teen can find bomb recipes in FIVE SECONDS

Five seconds is all it takes for a teen to find hundreds of thousands of websites listing detailed instructions for making bombs.
Some parents are now questioning their children's access to the internet after police foiled a plot hatched by four Northland teenagers that allegedly involved blowing up safes with bomb recipes downloaded from the internet and ordering weapons online.
The revelations have prompted internet experts to urge parents to take a closer interest in what their kids are up to on-line.
To find out how easy it is to find risky information on the internet, we asked a 17-year-old to look for bomb-making recipes. Five seconds and a Google search for a simple phrase later, links to 2,440,000 websites came up on screen.
One website on the first page of hits listed recipes for everything from napalm to fertiliser bombs, some of which could be made from four household ingredients.
Everyday items such as vinegar, turps, fertiliser, peroxide, chlorine and cleaners are used in some of the recipes. Many included ingredients that could be bought from a supermarket for less than $25.
One website also included information on picking locks, making plastic explosives, letterbox bombs, landmines, firebombs, flame throwers and nitroglycerine.
Our test teen said most of his friends knew how to build bombs through searching for the information on the internet.
However, he said there was "a big difference between knowing how to do something and actually doing it".
And a long-time Whangarei science teacher agrees. Lloyd Thomas was a science teacher for 30 years and says information on how to make explosions has been readily available for generations.
Mr Thomas said boys seemed more interested in making explosions and loud bangs than girls, and some teachers used this as a way of getting kids to take an interest in science.
"It's always been relatively easy to make bombs. In my youth we knew the recipe for making gunpowder. It wasn't hard to find and nothing has changed in that respect ...
"It's not the availability of the information that's the problem, it's the attitude and intention of the person with that information. It's like driving a car. They are wonderful things and you don't have to drive them fast and dangerously, but some people do that."
Mr Thomas did not think access to information on the internet should, or could, be controlled by legislation. Good parenting, and parents taking an interest in what their kids were doing on the internet, was more likely to help.
* Suspects surprise principal
A Northland principal says four teenagers involved in a plot to blow up a safe, buy guns via the internet and seek revenge were not troublesome students.
Legal reasons prevent the Advocate naming the principal, school or youths involved in a plan police describe as disturbing and ``like a plot from a B-grade movie'.
The principal confirmed all four had been at the school and two were students at the time police foiled their plan.
Police alleged the youths stole chemicals from the school and planned to use instructions from the internet to build a bomb to blow up the Te Hana petrol station safe.
The money would pay for firearms bought via the internet.
While police said the plan had "an air of unbelievability", they were treating it seriously.
The principal said the two students had been suspended as soon as the school became aware of a burglary in which six new DVD players and three laptop computers had been taken.
The school's board of trustees met during the school holidays last week but he would not reveal the outcome, as the school was "in wait mode" while police investigations continued.
He said if he had been asked to guess which students had been involved, he would not have placed the four youths at the top of his list.
"They'd been involved in minor stuff but not really what I would call trouble."
The school was going to review how chemicals were stored, but he believed the plot was an isolated incident.
"Everything is hypothetical and seems to be hearsay, but it is concerning," he said.
