Why doesn't the hot air escape out of the bottom of a hot air balloon?
Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.
What causes heat in air molecules in a hot air balloon to carry thermal energy to the top of the balloon?
Convection. :)
What is the Parachute Vavle Cord in a hot air balloon?
It controls the parachute at the top of the balloon. By pulling down on the cord it opens the top, letting hot air out and controlling the decent

Put a balloon over the top of the test tube. If the balloon inflates, it is from the gas that was produced.
If you put water yeast and sugar in a bottle and put a balloon over the top the balloon will inflate. Will it inflate if you do NOT put sugar in it If not will anything happen at all?
Yeast eats the sugar giving off CO2 which is a gas that will inflate the balloon. Added: But since carbon dioxide is heavier than air this balloon gas will never reach the 'top'
How come when you put water in a balloon and you put it on top of lit candle it won't pop?
The balloon easily withstands the flame because of the high heat capacity of the water.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
What should you make a drum out of?
A large or small can from vegetables or beans, And put A balloon on the top
