Coir isn't actually soil - it's made from coconut husk fibre, and scientists (and kit-makers!) love it because it holds moisture without going mouldy or messy indoors. Your butter bean seed already carries its own packed lunch of stored energy, which is why it can start sprouting with just a bit of water and warmth, even before it's grown real roots.

You get to learn all about seedlings and grow your very own butter bean!

• Once your seedling has a few leaves, move its pot somewhere it'll get a bit of sunshine each day and keep the coir pellet damp (not soaked!).
• Snap a photo every few days - it's wild how much can change in a week.

Real Venus flytraps snap shut in under a second when something touches their trigger hairs twice. Can you build your pretend flytrap so its "jaws" close in one quick snap, just like the real thing?
