Circles are quite useful when we go skateboarding, and are called "pipes" and "half pipes".

Here is a quick video of some Skateboarding inside a pipe.



Here is some more skating inside a pipe, but this time with an awesome full circle loop at the end.



In Skate Boarding, and BMX Bike riding, doing a full rollercaster style loop is called doing a "Loop of Death", (for reasons that will become apparent a bit later on).

Here is a video of two slateboarders making it around the full circle "Loop of Death":



But before you think about trying this at home, perhaps you should check out this video:



BMX bikes and Motorbikes have done some successful full circle Loops.

Here is a great effort from some guys I'm sure you will all instantly recognise:




So we've seen skateboards and bikes do full circle loops, but what about something bigger, like a car?

Here is a failed attempt to have a Car do a full circle Loop:



But here is "Fifth Gear's" Loop the Loop high quality video of a car successfully making it. It gives the math that was used as well. In fact they set a new world record doing it.



Now for something completely mad involving circles that happens in England at Gloucestershire every year.

This one involves a big round circular cheese being rolled down an insanely steep hill, with the competitors chasing it downhill at full speed.




Let's finish off spreading a bit of culture around the globe, by featuring some classic Australian "Circle Work" that country boys do in their Utes:



Well I'm feeling quite dizzy after that final round of circles, and so I won't be doing any circle work in the ute today mate.
