Hypothesis
If we put an egg in a hypotonic solution for diffusion to happen then the egg will expand because there are too much water on the outside, which causes diffusion to happen to reach equilibrium.
If we put an egg in a hypertonic solution for diffusion to happen then the egg will shrink because there are lots substances in the water outside which means water has to diffuse mostly out of the egg to reach equilibrium.
