Lightning Storm in a Jar
Ingredients:
– 1 clear glass or plastic jar with lid
– Water
– Vegetable oil
– Alka-Seltzer tablets or fizzing tablets
– Flashlight or small LED light (optional)
– Blue food coloring
– Yellow food coloring
– Dropper or spoon
– Funnel (optional)
Directions:
1. Start by filling the jar with water until it’s about one-third full.
2. Using the dropper or spoon, slowly drizzle in vegetable oil until the jar is nearly full. You will notice the oil will float on top of the water.
3. Add a few drops of blue food coloring into the water layer, followed by a few drops of yellow food coloring. Observe how the drops create a swirling effect in the water.
4. Break the Alka-Seltzer tablets into small pieces. Drop them into the jar one at a time and watch as they fizz and create bubbles that rise through the oil layer.
5. (Optional) Shine a flashlight or small LED light through the jar to enhance the visual effect of the swirling colors and bubbles.
6. Enjoy observing the fascinating reaction as the colors swirl and the bubbles rise and fall.
Tips & Variations:
– Experiment with different colors! You can use other food coloring combinations to create unique effects, like red and green for a festive-themed jar.
– If you want to keep the experiment going, simply add more pieces of Alka-Seltzer tablets to reactivate the bubbling effect, or try using vinegar and baking soda for a different reaction.
