Now, grab your straw and insert it into the bottle’s opening. You’re almost ready for liftoff!

To launch your rocket, fill the bottle with a little water. Cover the opening with your hand, and when you’re ready, let go! The air pressure will push the rocket out, sending it flying into the sky.

Don’t worry if it doesn’t go far at first—experiment with different rocket designs and water levels to see what works best.

Simple Circuit Tester

Creating a simple circuit tester is a fantastic way to explore the basics of electricity and circuits. You’ll need a battery, a small light bulb, some wires, and a few clips. Don’t worry; you can find these items around your home or at a local store!

Start by connecting one wire to the battery’s positive terminal. Then, attach the other end of that wire to the light bulb’s metal base. Next, take another wire and connect one end to the light bulb’s side, and the other end to the battery’s negative terminal. If everything’s connected properly, the light bulb should light up!

This circuit tester is like a magic wand for discovering whether batteries or bulbs are working. If the bulb doesn’t light up, it might mean the battery’s dead or there’s a loose connection. You can also use your tester to check other devices around the house, like old toys or gadgets.

Just remember, electricity can be tricky, and safety comes first! Always have an adult nearby to help. Enjoy your experiments, and who knows? You might just uncover the next big invention!
