We searched for an alternative recycling method to deal creatively with the growing computer waste. This is our result:
What do you need for this experiment:
An old keyboard, cotton wool, a little water, seeds of garden cress, a folded paper, a screwdriver and a few sun beams.
First remove all the individual keys from the keyboard (easiest done with a screwdriver – but be careful).
Next step is to dress the inside with a soft cover of cotton. Don’t take too much, , otherwise the keys will not fit.
Now put back the keys. This was the most time-consuming part, because we wanted to put them back into the right place. Luckily we had a template.
The next step is to pour the cress seeds into the gaps between the keys. The best way we have achieved this was by folding a paper in half.
Now you only need a little patience, sunlight, and a healthy spray of water every morning, and after 3 to 4 days, the first watercress stalks will be visible.
It was interesting to observe what power the garden cress has, as it seemingly effortlessly pushes out some keys, which we had previously pressed in with great effort.
Only one keyboard was harmed during that experiment.
