oxygen is less dense than water thus it rises
a balloon float on water
Balloons are full of a gas called 'helium', which is lighter than air. The helium is trapped inside the balloon, that's what makes it float.
Fill a balloon part way with helium, make an animal out of it and have it float.
Heilum combined with the light material of the balloon make it as light as air making it float.
Helium goes into a balloon to make it float.
First, the balloon would float to the ground. After that, nothing special happens to the balloon because you filled it with oxygen.
In the banana are little pockets of oxygen in the peel that is also how they float!

because the hydrogen and oxygen react together creating water(the small droplets of liquid)
100% helium

The key word there is float. There is nothing in space for a hot air balloon to float on.
yes

Hydrogen or helium are used. As they are lighter than air that's why they float in air when filled in a balloon. Also, sometimes oxygen and carbon dioxide from your lungs, if you blew the balloon up with your mouth.
The balloon will either float or pop
