It is simple, you don’t need to have any weird ingredients, you can get everything at the grocery store, or even the corner store.
– vegetable oil – food color – Alka-Seltzer tablets – these aren’t expensive, you can get a lot of reactions out of one little box.
You want to add a couple inches of water to your clear glass. Adding food color will help you see what is happening better, using yellow, however, will not. We used blue, red, and green.
Add a few inches of vegetable oil to your jar. Just doing this alone is an experiment in its self.
Now, drop in an Alka-Seltzer tablet. Watch the reaction.
For smaller bubbles, break the Alka-Seltzer tablet into smaller pieces. For larger bubbles (which we had), you can drop the whole tablet (or more) into the glass.
