Abseil the Orbit for Street Child

Why not throw yourself off a tall building – in fact, the UK's tallest sculpture, 263ft high – for charity? There are strings attached: most importantly, the rope you abseil down, but also the requirement for you to raise £250 in sponsorship for Street Child, which will use the funds to help children in Sierra Leone and Liberia who have been orphaned by Ebola. There are numerous slots through the day, and you can take part with five friends (up to six people can jump every half an hour).

Note: you must be at least 18 years old to take part.
