Jas sports some safety goggles while making carbonic acid
How do you test for safety? Does it ever go wrong?
David: We take safety very seriously. We start with a discussion, where we try to imagine what might go wrong. For example, we were considering a helium balloon in a car activity, but it needed a rethink when we realised the balloon would probably end up floating in front of the driver.
We test activities thoroughly, remembering that kids are still developing their coordination. All kinds of things pop up at this stage – getting splashed with a little boiling marmalade was a bit scary, but not quite as bad as the time I set a battery on fire trying to make an electromagnet! We throw out or adjust activities that don’t pass testing.
We also do plenty of research, particularly with our chemistry activities. Prussian blue pigment doesn’t sound very scary, but ferric ferrocyanide sounds downright deadly. Turns out, it’s not too bad, and with the right precautions, you can use it to grow some wonderful crystals.
Jasmine: This testing process helps us select the correct safety icons, as well as the messages we write to let young readers know what hazards to look out for.
We also keep an eye out for anything that might be an environmental hazard, for example, checking if paper straws will work instead of plastic ones.
