Seed Bombs

EXPERIMENT

You will need: measuring cup (30 ml), 1/2 measuring

cup of plaster, 1 measuring cup of sand, 1/2 measuring

cup of ﬂower seeds, wooden spatula, plastic molding

tray, newspaper, 3 measuring cups of poing soil, 1

measuring cup of water, large plastic bowl

Cover your work area in newspaper. Put the

plaster, the sand, seeds, and the soil in the large

bowl. Stir the dry ingredients with the spatula

until they are evenly mixed. Be careful not to stir

up dust.

Gradually add one measuring cup of water and

mix it into a smooth dough, free of lumps. Add

more or less water depending on the dampness

of the soil you used. Shape the seed bombs right

away before the mixture gets too hard!

Either put the mixture into the molding tray or

make small balls out of it.

Let the seed bombs harden for a few hours. If the

weather and season are right, you can then throw

them outside right away! If you want to save them

longer, store them in a box. It should be dark and

dry, or else the seed bombs will sprout too soon!

Or you can wrap them in some gi wrap, label

them, and give them to your family and friends.

Leucanthemum Ircutianum

Common names: Aster, Daisy

Flower color: White outer

petals with yellow center

Lavatera Trimestris

Common name: Annual mallow

Flower color: White, pink,

magenta (mixed)

The soil and the water ensure that the seeds

have everything that they need to start to

grow. The sand and the plaster protect the

seeds and prevent your seed bomb from

coming apart too quickly.
