What is a Stick Bomb?

11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.

Fact or Fable? Most body heat is lost through the head

Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.

Carnivals Around the World

You might have heard of the carnival in Rio, but did you know that there are carnivals around the world – from Germany to Greece, USA to Italy?

Millie Slavidou explains where Carnival comes from on her blog

Long before the advent of Christianity, people held celebrations at this time of year. In Germany, they once looked forward to sending Hel, the goddess of the underworld, back down to her abode so they could herald the coming of the spring. In Greece, it was a time to worship the god Dionysus. With the arrival of Christianity, the celebrations continued, but changed in nature, gradually becoming more and more linked to the new religion. The Carnival is held in the period before the start of Lent, and Lent is the time when good Christians were supposed to fast, to abstain from meat 

In the UK, we don’t celebrate Carnival, but we do prepare for Lent – that is what Pancake Day is all about, after all. Traditionally, pancakes were made to use up the eggs, fat, and butter, that were not to be eaten during Lent!
