A tiny plan for your day

Estimated time: 5 min to prepare · 8 min to make · 2 min to tidy. Then water and watch. Plus waiting time: a week of watching. It's fine to stop early.

Before you start

What you’ll need

  • An empty, clean eggshell, top cracked off by an adult
  • Cotton wool
  • Cress seeds
  • Felt pens and an egg box

Let's begin

Five simple steps

That's the whole activity. Tick each step off as you go, and stop whenever you like.

  1. Little one leads

    Your child draws a face on the eggshell.

  2. Push damp cotton wool inside.

  3. Sprinkle cress seeds over the top.

  4. Sit it in the egg box on a sunny windowsill.

  5. Keep the cotton wool damp. Check each morning for hair!

All done!

That's every step. However it went, you made a little moment together.
