The Big Bloody Experiment

It’s something we all have, but do you know what’s in your blood and how it works?
Dr Rob and Australian Red Cross Lifeblood team up to explore kids’ fascinations
with blood, scabs, bruises and wounds.
Part special effects workshop, part science experimenting but one bloody good time!

How do I take part?

This will mean you get any updates from us and links to the resources when they are released, ensuring you miss none of the fun.

How does it work?

The Big Bloody Experiment is a great way to combine science, art and fun for the whole class. There will be easy to follow videos explaining what to do, the science behind it all, links to the real world and some teacher tips.

There will be a broad range of blood related stuff covered, including:

  • what’s in our blood
  • scabs and why they form
  • the weird shades of bruising
  • how blood changes in the animal kingdom
  • and lots more


    Ideally everyone does it around the Australian Science Week (mid-August), but it is fine to run your own timetable.

    How long will it take and what do I need?

    It can all be done in a hour or two, and there are only a few grocery store items required. 

    Make the fake blood and skin, get some real science along the way. 

    DIY ball of squishy skin.
    It looks painful, but it is all fake bruise.
    Well, it looks like a beaker of blood…

    Is this really science?

    Yes indeed. Accompanying the special effects workshop is a load of science behind blood and its importance to us, as well as extension ideas for the keen ones.

    And as for making the blood and skin and bruises, there will be some experimenting there too, trying to get just the right shade, viscosity and texture.

    You can even share your results (via some great pictures) with other schools and the world.

    Is all this free?

    Yes. All the resources for this bloody good time will be made available to the registered schools.


    • Fun engaging and (yes) educational event to run during National Science Week
    • Great to do with a whole class
    • Free lessons provided (they won’t feel like lessons)
    • Suitable for Primary or Secondary students 
    • It is easy to organise and minimal effort/materials required to take part
    • Kids will love it.


      • Hmmm can’t think of one…ok, maybe the clean up?

      And special thanks to…

      If you only do some science once a year, that is still better than not doing it. So get stuck in and find out what your brain has to offer.

      They have no nucleus and look like a donut. But, we’d certainly be lost without them and the oxygen they carry around us.

      The Big Bloody Experiment is being hosted by Dr Rob and Experimentary, because we love science (you’re welcome).
