Why shouldn't you let helium balloons into the air?

Why do helium-filled balloons and hot-air balloons float in the air?
It is because helium is 6x lighter then air, therefore helium filled balloons float. Hot air balloons float because hot air rises. (because it's lighter than normal/cold air) Answer: Hot air balloons are filled with hot air (that's pretty obvious) and are surrounded by cooler air. Cooler air is more dense than hot air so the balloon weighs less than the air it displaces. This gives it a buoyant upward force. This is the same as holding a pop bottle filled with air under water. Let it go and it rises up. As you go higher into the air the air becomes less dense. The balloon will rise until the cool air around it is the same density as the air in the balloon.

Party games for 13 year old girls?
For an active inside game, tie a balloon around each girl's ankle and have the girls try to pop each other's balloons without getting their own popped. This game will likely be noisy as the balloons pop and the girls giggle. For a more grown-up feel, consider a preplanned game of truth-or-dare. Inflate balloons without tying them; then, write out age-appropriate truths and dares, and let the air out of the balloons. Let the girls randomly select the balloons and inflate them to see their truth-or-dare.

Does gravity act on gases as it does liquids and solids?
Yes, gases just like all other materials have density. This is why a balloon filled with helium will rise to the ceiling. It floats because all of the air around it is denser than the helium in the balloon. If you let the helium balloon go outside, it will rise to an altitude that is equal in density as the helium.
