You can use it to calculate the difference in diffusion rates when dealing with different SA;VOL ratios. The greater the SA;vol ratio, the faster the diffusion. You can do this using Hydrochloric Acid and submerging the cubes in it whilst timing how long it takes for it to permeate the agar jelly cube.

Acid can move through agar jelly by a process called diffusion, where molecules move from an area of high concentration to an area of low concentration. The acid molecules will spread evenly throughout the agar jelly until they reach equilibrium.
Amylase would spread into the agar jelly through diffusion, as the enzyme molecules move from an area of high concentration to an area of low concentration. The amylase will break down the starch in the agar jelly into smaller molecules like maltose, which will diffuse away from the point of origin.
Agar jelly has good moisture retention properties, making it an effective barrier against dehydration. However, it is not an effective barrier against oxygen transmission and can allow gases to pass through. Agar jelly can also absorb water and become softer over time, which may affect its barrier properties.
Put agar jelly in a petri dish to sterilize the dish and then use something like a sterile inoculating loop to put the bacteria on the jelly. Then, seal the petri dish but make sure it is not airtight.
Agar-agar
Agar jelly is a type of jelly using the seaweed gelatin know as agar agar as a thickener. Usually it is used in Europe because it does not appeal to the American pallate for the fact that it does not melt in your mouth like gelatin or pectin.

The jelly like substance is agar and is produced from seaweed. In the laboratory, the agar is placed in a Petri Dish.

A nutrient jelly for growing bacteria is a solid medium made of agar and nutrients such as amino acids, vitamins, and minerals that bacteria need for growth. It provides a surface for bacteria to grow and form colonies that can be easily observed and studied in laboratory settings.

An agar block is a solid medium made from agar-agar, a gelatinous substance derived from seaweed. It is commonly used in laboratories to culture and grow microorganisms such as bacteria, fungi, and other small organisms for research purposes. Agar blocks provide a stable matrix for microbial growth and are easy to work with in scientific experiments.
Agar is often used in place of gelatin (which is derived from collagen). In the UK its possible to buy vegetarian Jelly (jello, I believe its called in the US) which is agar based. Agar comes from seaweed.
