Adhesion – the physics of Space Gardens
Adhesion is the force of attraction between atoms or molecules of different substances. One example of this is the adhesion between glass and water molecules – resulting in the creation of a meniscus.
Adhesion occurs in space, but other forces (like gravity) are less powerful. This allowed Nikolai Budarin to take this image in the Russian Lada greenhouse on the International Space Station (ISS).
The stalk supports a drop of water – without bending under its weight. Furthermore, a bubble of air sits suspended, trapped within the droplet
In space, however, the air bubble doesn't rise because there's no buoyancy. The force of molecular adhesion sticks the droplet to the leaf – there's no other force to pull it off.

You say you love rain, but you use an umbrella to walk under it.
You say you love sun, but you seek shade when its shining.
You say you love wind, but when its comes you close your window.
So that's why I'm scared, when you say you love me.
