What's in Our Blood?

Come and discover what your blood is actually made of and how it keeps you healthy every single day.

Did you know that in just one tiny drop of blood, there are 200–300 million red blood cells? That's more than the number of people living in Brazil!

At this exhibit, meet the amazing team of tiny heroes living inside your blood. These incredible little characters work around the clock to fight off germs, patch up cuts and scrapes, and deliver food and oxygen to every part of your body.

Think you know your blood facts? Play a true or false challenge and see how much you really know! You can also find out about the exciting science happening at Imperial College London, where researchers are working to solve mysteries about blood and the illnesses that affect it.

Finally, get creative and help build a giant blood-themed sculpture! Bring your best crafting skills and help us make something amazing.
