If you are asking about a bubble in a liquid, the answer is that the bubble has lower density (the gas inside is "lighter") than the surrounding liquid.
If you are asking about a soap bubble, the answer is that air currents carry the bubble up. The bubble itself is not lighter than air (unless filled with another gas) but the film making the bubble is so thin and light that air currents can move it easily.
Yes (if you haven't burst all the bubbles).
It depends on the age of the egg. An older egg is likely to float as the air bubble in the egg hows larger as the egg dries out. This used to be a test for separating fresh from old eggs in general stores. Even a fresh egg (even though it doesn't float) will orient itself bubble end up in a pan of water.
Straws don't really float they will sink because they will fill up with water and sink.
you jump up high and float
It is bubble wrap. I did that in a science experiment. Bubble wrap wouldn't be comfortable to wear so the next runner up is wool.
The density of the bubble is lower.
yes
Make sure the balloon is aimed toward the bubble, the cut the rope, it will go into the bubble then float up and the dino will eat it.
Yes, Glinda the Good floats around in a bubble :D
and what. air bubble system? or Hydrometer??
Answersoap does float if it is filled with air
Yes (if you haven't burst all the bubbles).
Its average density is a lot less than water
In order to float, the bubble hitches a ride on a gas that is slightly denser than the air trapped inside of it: carbon dioxide!
A bubble of air is in a small slightly curved tube of alcohol. The bubble will float at the highest point and indicate level or not level.
*fizzle* or *bubble* i really dont know that is a difficult one
float up
