Foam:
The foam is a colloid in which a gas is dispersed in liquid medium.
Example : Soap bubbles, Shaving cream.
Gel:
The gel is a semi solid colloid in which there is a continuous network  of solid particles dispersed in a liquid.
Examples are : Jellies, Hair gel.
Because all these above mentioned mixtures are all colloidals,
The particles are big enough to scatter light.
The size of particles will be between 1nm to 100nm in diameter.
Most of the collodial particles cannot be even seen with a microscope.
Colloidal particles cannot be seperated through filtration.
