Makuro's Glow Spring Lab: 16-Pack Glow-in-the-Dark Cat Springs

Makuro has been studying these springs for three days. She has a theory. She will not be sharing it.

Sixteen colourful jelly-look plastic springs that boing, bounce and skitter across the floor in ways no cat can predict. Leave them in the light and they glow in the dark, so the experiment can continue after bedtime. A big value pack, because half of them will end up under the sofa.

Crew verdict: "Fascinating. Hypothesis: if I push it off the table, it falls. Testing again." (Makuro, Head of Strategy)
