No. Air or helium goes inside the balloon.
the inside of it
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
The pressure inside the balloon has to exceed the pressure outside the balloon.
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.

The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.

This could be easier to do if you have someone help you. First, stretch open the mouth of a balloon and keep it stretched. Second, put another balloon inside the open balloon. Third, unstretch the balloon, so the balloon inside the balloon stays inside. If you want both balloons to be full of air, blow air into the smaller balloon to the appropriate size. Tie it so the air won't escape. Then, blow into the outside balloon, so it will grow bigger than the inside balloon, then tie it. The outer balloon may be a clear and see-through, so people can see through it and notice the smaller inner balloon to admire your creation.
if we keep a pumpkin inside a balloon the balloon will not fly and will burst
more gas particles increases the pressure inside the balloon expanding it, since gas particles hit the inside of the balloon.
