Building the Catapult
Now that you have all the materials, let's start building your marshmallow catapult! First, stack seven craft sticks together and wrap a rubber band tightly around each end. This forms the catapult arm.
Next, stack two craft sticks and wrap a rubber band around only one end. Slide the five-stick bundle in between the two sticks, about 3/4 inch from the rubber band. This creates the base.
To attach the arm to the base, slide a craft stick between the two sticks of the base on the opposite side of the five-stick bundle. Wrap a rubber band where the arm and base intersect, joining them together.
Finally, glue the bottle cap to the top of the arm at the end without the rubber band. This will be the launching pad for your marshmallows.
Your catapult is now ready! To launch, place a mini marshmallow in the bottle cap, hold down the base with one hand, and press down on the arm with the other. Release the arm and watch your marshmallow soar!
Experiment with different launching angles and positions for maximum distance and accuracy.
Testing and Experimenting
With your marshmallow catapult built, it's time to put it to the test and see how it performs. Set up a target area and measure the distance from your catapult. Place a marshmallow in the launching cup and pull back the arm to varying degrees to test its range and accuracy.
Keep track of your results in a notebook, recording the angle of the arm, the distance the marshmallow traveled, and whether it hit the target.
- Experiment with different arm angles to see how it affects the marshmallow's trajectory and distance.
- Try using marshmallows of different sizes and weights to observe any changes in performance.
- Investigate how the catapult's height from the ground impacts the marshmallow's flight.
- Test the catapult on various surfaces, such as grass, concrete, or carpet, to see if it makes a difference.
- Challenge your friends to a marshmallow launching competition and compare your catapults' performances.
Gravity-Defying Water
Gravity-defying water experiments are a fascinating way to explore the principles of surface tension and cohesion.
You can create a simple setup using a glass, water, and a piece of cardboard. Fill the glass to the brim with water, place the cardboard on top, and quickly flip the glass upside down while holding the cardboard in place. Remove your hand from the cardboard, and you'll see that the water remains in the glass, defying gravity!
This happens because water molecules are attracted to each other (cohesion) and to the glass (adhesion). The surface tension created by these forces is strong enough to overcome the pull of gravity, keeping the water in place.
You can also experiment with different liquids, like oil or syrup, to compare their surface tension and observe how they behave differently.
Homemade Lava Lamps
To create your own lava lamp, you'll need a clear glass or plastic bottle, water, vegetable oil, food coloring, and an effervescent tablet like Alka-Seltzer.
First, fill the bottle about 1/4 full with water, then add vegetable oil until the bottle is nearly full, leaving some space at the top.
Next, add a few drops of food coloring to the bottle and watch as the color sinks through the oil and mixes with the water at the bottom.
Materials Needed
You'll need a few simple materials to create your own enchanting lava lamp at home. Gather these items:
- A clear glass bottle or jar with a tight-fitting lid
- Water
- Vegetable oil
- Food coloring
- Effervescent tablets (such as Alka-Seltzer)
Make sure the bottle or jar is clean and dry before you begin. You'll want a container that's tall enough to allow the "lava" to flow and move around freely. The size of the bottle will determine the amount of water and oil you'll need.
When selecting your food coloring, remember that the color will be diluted by the water, so choose vibrant shades for the best effect.
Effervescent tablets can be found at most drugstores or supermarkets. They'll provide the chemical reaction necessary to create the enchanting bubbling and movement within your lava lamp.
With these materials ready, you're set to start experimenting and creating your own colorful, mesmerizing lava lamp.
Get ready to immerse yourself in the fascinating world of density and immiscibility as you explore the science behind this classic decorative piece.
