The Great White Shark

Great White Sharks are probably thought of as one of the scariest creatures in the world - and you'd probably be right! They can actually be found in the coastal waters of all the main oceans.  Having said that, shark attacks are incredibly rare, and even rarer that they turn out to be fatal. They are actually huge, they average around 15ft long but some have recorded at 20ft! They're also very speedy, they can swim up to around 15mph! Their blue-grey color actually helps them to blend in with the color of the sea, particularly when they're viewed from above.

In the Oceans, they actually remain mostly threatened, their only natural predators are the killer whale, but they are however threatened by us, so much so they're actually classed as vulnerable on the endangered species list.

Even though we might not be able to directly help the Sharks, one thing we can do to help is to not buy the 'products' people make from them from their jaws to other products made from their fins.

Together, we can save the Great White Shark.

#GBBO | Why do biscuits go soft?

As Great British Bake Off returns tonight for episode 5 I thought I'd look at the science of baking. Unlike bread, most biscuits tend to go soft if they aren't eaten quickly enough. Biscuits are baked to have a low moisture content so they're crunchy. However if they're left out for too long they start to absorb moisture from the air so if you keep your biscuits in an air tight container they'll stay fresher for longer.
