I made an emulsion in a glass. It looks very nice and if you shake it, the colors will move.

Step 1: Materials and Tools
You will need:
- a hot glue gun
- a board
- a pencil
- a needle
- a spoon
- syrup/food coloring (It's esential that the syrup doesn't dissolve in the oil.)
- the glass lid of a glass jar (I used a coffee-jar. The lid must have a plastic underside)
- a toothpick (not on the foto)
Step 2: Mixing
First, mix the water and the syrup, so you will get a red liquid. You can use the spoon if you want.
Step 3: Preparing the Lid
Take the glass lid and pierce the plastic part of the lid with the needle. There is a small hole in the lid now. Enlarge that hole with a pencil.
Step 4: Fill the Lid
Pour some of the oil on the plastic surface. Press with the toothpick on the surface, but don't pierce the plastic. By pressing, you will create a low pressure. That will cause that the lid sucks the oil in the lid. Repeat this till you have a third of the lid filled. (The foto's are from pouring the red water, but with oil, it's exactly the same.)
Step 5: Fill the Lid
This is exactly the same as the last step, only you use the red water instead of the oil:
Pour some of the red water on the plastic surface. Press with the toothpick on the surface, but don't pierce the plastic. By pressing, you will create a low prssure. That will cause that the lid sucks the red water in the lid. Repeat this till you have a third of the lid filled.
Step 6: Close the Lid
Glue the hole, so it's closed. Make sure you put enough glue in/on the hole, so it won't leak.
Step 7: Watch It Move
It's finished. You can shake it and watch the liquids move.
