Children love watching things grow but most do not have the patience, time just tracks slower when you are a child. I read somewhere once that its because of how we process time and memories, 1 day/1 year is a much larger number than 1 day/21 years its all relative; and yes I'm still 21 ;)
Anyway I digress, welcome wonder seed, otherwise known as Cress. This stuff will sprout in a day or two and give you a head of hair in a week. Perfect for my little impatient gardeners.
You will need:
Empty egg shell
Something to sit your cress head in (egg box or shortened toilet tube works well)
Create your face, have your child draw onto the egg with the sharpie. Show them that the open end is where the hair will grow from.
Fill egg with cotton balls.
Sprinkle cress seeds all over the top of the cotton balls. (You don't really need the entire packet as Buba did but try telling that to a 5 year old).
Water so that cotton wool is moist and stand in a sunny spot. Keep the cotton wet by watering when needed. you will see the seeds germinating within 24-48 hrs.
By day 3
By Day 7
And the best bit about cress is that once they've grown the hair they can pick some and add it to a egg and cress sandwich knowing they've grown their first vegetable.
