Rainbow in a Jar is a simple yet mesmerizing science experiment that demonstrates the concept of liquid density. You will need a clear glass jar, honey, corn syrup, dish soap, olive oil, rubbing alcohol, and food coloring in red, blue, green, and yellow. Follow these steps to create your own rainbow in a jar: 1. Carefully pour honey into the jar until it fills about 1/6 of the jar. 2. Slowly add corn syrup, dish soap, and olive oil in layers on top of the honey. 3. Gently pour rubbing alcohol into the jar to create the final layer. 4. Add a few drops of food coloring in each layer to represent the colors of the rainbow. 5. Watch in awe as the different layers of liquids form a beautiful rainbow effect in the jar.

Elephant Toothpaste is a classic science experiment that showcases an exothermic reaction between hydrogen peroxide and potassium iodide. To create your own foamy explosion, you will need a plastic bottle, hydrogen peroxide, dish soap, food coloring, dry yeast, and warm water. Follow these steps to make your own Elephant Toothpaste: 1. Pour hydrogen peroxide, dish soap, and food coloring into the plastic bottle. 2. In a separate container, mix warm water and dry yeast together. 3. Quickly pour the yeast mixture into the bottle containing the hydrogen peroxide solution. 4. Stand back and watch as the foam erupts from the bottle in a spectacular chemical reaction.

Invisible Ink is a fun science experiment that explores the concept of acids and bases. You will need a white paper, lemon juice, a cotton swab, a heat source (such as a light bulb or iron), and a revealing agent like iodine solution. Follow these steps to create your own invisible ink message: 1. Dip the cotton swab in lemon juice and write a message on the white paper. 2. Allow the lemon juice to dry completely, turning the message invisible. 3. To reveal the message, heat the paper gently using a light bulb or iron. 4. Watch as the lemon juice turns brown due to the heat, making the message visible.

Tornado in a Jar is an exciting science experiment that demonstrates how tornadoes form in nature. You will need a clear jar with a lid, water, dish soap, and glitter. Follow these steps to create your own tornado in a jar: 1. Fill the jar with water until it is about three-quarters full. 2. Add a few drops of dish soap to the water. 3. Sprinkle glitter into the jar to act as a visual representation of the tornado. 4. Securely close the lid and swirl the jar in a circular motion to create a vortex. 5. Watch as the glitter swirls and forms a mini tornado inside the jar.

Balloon Rocket is a thrilling science experiment that demonstrates the basic concepts of thrust and propulsion. You will need a long piece of string, a straw, tape, and two balloons. Follow these steps to build your own balloon rocket: 1. Thread the string through the straw and secure it between two points in the room. 2. Inflate one balloon and tape it to the straw to act as the rocket. 3. Inflate the second balloon and hold it closed with your fingers. 4. Release the second balloon, allowing the air to propel the rocket along the string. 5. Observe the balloon rocket in action and explore different variables for speed and distance.
