+Reminders

The amount of essential oil added depends on the smell of the gelatin and the intensity of the scent needed. If the gelatin is not unflavored, more spices should be add to cover the smell. On the contrary,if the glue does not have a smell, less amount of oil need to be added.

The amount of colorings added depends on the color the creator wished.

Every product might has different amount of time for the shape to form. This also depends on the amount of the product. The recommended solution to avoid getting it frozen is to check the state of the gel every other 30 minutes.

+First Observation

Time: around 2: 30p.m.

This is its look right after the mixing process finishes. The color of the liquid is blue. It is also very translucent. It has a very strong scent. The jar has nothing else inside other than the liquid; It is very clean.

+Second Observation

Time: around 3:00 p.m.

The state of the liquid begin to change. It is becoming more dense. Also, the mixture barely moves while tilting the jar. The color is less translucent comparing to the beginning. The smell is still very strong. The mixture closer to the bottom part of the jar is becoming gel. However, most of the it is still in the form of liquid.

+Final Product

Time: around 5:30 p.m.

After a few hours in the freezer, the shape of the gel is formed. The product has a very low temperature. The texture is very dilute. Additionally, the color gel becomes lighter comparing to its look before freezing. The product is opaque. There are scrums of ice around the inner edge of the jar. The surface of the gel does not look smooth.

+Last Observation

Time: around 8:00 p.m.

After defrosting the gel by putting it under the situation with indoor temperatures, the product start to melt again. Even though only the surface becomes liquid, this might still be a huge issue my partner and I need to solve.
