Volcano Attempt Turned Bubbles

I had heard mixing Water, Vegetable Oil and Alka-Seltzer together results in a really neat volcano.  We did not have any Alka-Seltzer on hand so we tried it with Efferdent.  Sadly, no volcano action.  But the Efferdent did create a lot of fizz so we improvised and just poured the contents into a bowl and made bubbles.

Supplies: Water, Vegetable Oil, Efferdent Tablets, Food Coloring, Bottle, Funnel, Pan/Bowl, Straws

Fill bottle half way up with water and then add vegetable oil to within an inch of the top. Add food coloring for extra fun.  For a volcano effect break up Alka-Seltzer Tablets and drop them in.

We used Efferdent Tablets that did not create a volcano so I grabbed a bowl and poured out the bottle so we could see the fizziness.  (My guess is that Alka-Seltzer must dissolve much quicker and therefore works better). 

She kept adding drops of food coloring on top of the fizzy spots which quickly turned into a dull mess of colors but she liked it.  She really enjoyed squishing the little tablet pieces and watching them fizz up. 

She wanted big bubbles so I pulled out the straws.

Daddy can always be counted on for big bubbles!

We had fun with this experiment but I really look forward to actually producing a volcano.  Alka-Seltzer is on the shopping list so I should have pictures and a description of the volcano up soon (cross fingers that it works).
