They achieve liftoff by filling up the envelope with hot air, hot air is less dense and so it rises. To lower the hot air balloon, they will pull a string to release the hot air.
The thrust of a rocket on liftoff can vary depending on the rocket's design and size. For example, the Falcon 9 rocket produces about 1.7 million pounds of thrust at liftoff.
During liftoff, the two main forces acting on a rocket are thrust and gravity. Thrust is generated by the rocket's engines, pushing it upward, while gravity pulls the rocket back towards the Earth. These forces must be balanced for the rocket to achieve liftoff and ascend into space.

To create a beautiful balloon arch for a party, start by inflating colorful balloons to the desired size. Tie the balloons together in a pattern, alternating colors and sizes. Use a sturdy frame or structure to attach the balloons to, shaping them into an arch. Adjust the placement and tightness of the balloons to achieve the desired look.
