Some options to make bubbling liquid:

Put a piece of "dry ice" (frozen carbon dioxide) to the liquid.
It make it bubble very much, especially if the liquid is cold.
The liquid is wel drinkable, because it just get sume bubbles
like limonades have. Be careful that the "dry ice" is itself
dangerously cold.

Pour liquid nitrogen and ater together. This makes very much
bubbles. Nitrogen is not poisonous in any way (most of air
is nitrogen). Liquid nitrogen is dangerously cold, so you must
wait until all the liquid has vaporized before drinking, because
liquid nitrogen is very cold. Very smal amounts of it does not
hard much, but larger amounts are dangerous. 

Open a bottle off cold limonade (or any carbonized drink)
and let is stabilize so that it does not bubble much. 
If you now move the limonade bottle much or add something
suitable to it (ice,sugar,quite many things) usually starts 
to bubble again. Might not be as spectacular as the others,
but might work as an effect.
