A colloid is cloudy and thick and will not allow light to pass through, whereas a suspension is clear and transparent and lets light pass through it.

A torch can be used to test a colloid by shining the light through the colloid. If the colloid scatters the light making it visible (Tyndall effect), then it is a colloid. This is because the particles in the colloid are large enough to scatter light, unlike particles in a solution which are too small.

How could a torch show if you have a colloid or a solution?

Shine the torch through the mixture. If the light passes through the mixture without scattering, it is likely a solution as the particles are small and do not block the light. If the light is scattered and the beam is visible, it is likely a colloid due to the larger particle size that causes light scattering.
