The Flying Tea bag

Flying Tea Bag

The flying tea bag trick is an extremely easy trick only using a couple of household objects and is very quick. But how does it fly up into the sky? Let me explain

Once you’ve set up the whole thing and set the tea bag on fire. While it's on fire the energy from the flames is transferring to the air molecules making the air molecules move really fast. Also because it's in a cylindrical shape and your burning it from the top the air down the bottom is trapped.

So the air molecules are moving around more a lot more and are taking up a lot more space making the air denser. Therefore is under pressure and sometimes things pop when they are under pressure. So it pops ever so slightly, but then the cold air from the outside gets in and goes in so fast that it lifts the tea bag off the ground.

So if you ever chose to do this trick just try to imagine all those tiny molecules at the bottom of the tea bag squirming around trying to find a way out of the burning apocalypse.

How chocolate is made

One day in literacy I watched a video talking about how chocolate made. This is another interpretation.

Throughout history, people have eaten chocolate for many reasons like for a tasty treat or if you break up with someone. This is the way for Hundreds of years chocolate has been made.

Farmers need to collect cocoa beans that have been growing for 6 months on a cocoa tree in some part of the equatorial forest. Once they are harvested and taken from the cocoa pod the beans are left and covered for fermenting and a left for 5-7 days. Then are dried for 6 days.

At the collection centres the beans are weighed and checked for quality, they are then put into bags and shipped by either boat or land vehicle and are sent to the cocoa factory.

In the factory, the beans are washed, dried and split up into nibs. The nibs are then roasted and ground into a thin and fine liquid called cocoa liquor. After that cocoa liquor can be processed into cocoa butter and cocoa powder.

Making the chocolate, The cocoa liquor is then mixed with cocoa butter, sugar and milk and is put through a type of process called conching. Conching makes the chocolate smooth and creamy. Other ingredients may be added after being conched. Then the chocolate is delivered to a packaging facility. After packaging they are then shipped to the stores and sold.

Chocolate is delicious, sweet, smooth and all round the best type of food ever. You can get hundreds of different types chocolate from numerous chocolatiers.
