Turn a balloon, straw and length of string into a small home science laboratory. Learners investigate air pressure, thrust, direction and friction, then plan a fair test and use their own evidence to improve the rocket. The course is self-paced and designed for an adult and learner to complete together using ordinary household materials.

Future Forge lesson formula
Learn what a force is; see how escaping air makes the balloon move; introduce action and reaction; watch a balloon rocket demonstration.
Make a simple balloon rocket; predict how far it will travel; test it.
Experiment with balloon size, rocket shape, amount of air, weight and string length; record and compare results.
Redesign the rocket to travel further, travel faster, stay stable, or carry a small payload.
Present the best design and explain what was changed and why.
A balloon-powered rocket and an investigation into how to make it travel further or faster.
This course works best when an adult helps to make the launch line secure, keeps the test area clear and supports the learner with tying balloons if needed. Encourage predictions and questions rather than supplying the answer: the purpose is to notice evidence, not to achieve the fastest possible rocket.
Adult supervision is required. Check whether anyone taking part has a latex allergy and use a suitable latex-free balloon if necessary. Keep balloons and broken balloon pieces away from babies, young children and pets. Do not overinflate balloons, aim them at faces, attach hard or sharp objects, or release them outdoors. Secure the string at a sensible height, keep the route away from stairs and doorways, and remove or cut the line down as soon as testing is complete.
Work independently through a short, structured introduction and complete one practical outcome at home.
Paid live lessons add personalised guidance, discussion and access to the wider project library. This free course does not make the full catalogue free.
