Here is a concise summary of the 12 easy home experiments:
**Experiment List with Brief Description**
1. **Color Changing Flowers**: Observe capillarity by adding food coloring to water with cut white flowers.
2. **Milk Explosion**: Demonstrate surface tension using milk, food coloring, and dish soap.
3. **Magnetic Coin Rotation**: Showcase induced magnetism with magnets, coins, and a straw.
4. **Iron Filing Attraction**: Visualize magnetism with iron filings, a bottle, water, and magnets.
5. **Balloon Piercing Challenge**: Safely pierce a balloon with a toothpick using oil to reduce tension.
6. **Refraction Experiment**: Illustrate light refraction using a glass of water and colored lines.
7. **Rainbow Formation**: Create a rainbow through capillarity with a napkin, markers, and two glasses of water.
8. **Pencil through Plastic Bag**: Demonstrate molecular behavior by inserting a pencil into a sealed, water-filled plastic bag.
9. **Tangerine Buoyancy**: Compare the buoyancy of tangerines with and without peels.
10. **Homemade Lava Lamp**: Mix water, oil, food coloring, and an effervescent tablet to create a lava lamp effect.
11. **Heat-Resistant Balloon**: Prevent a balloon from popping near a candle by filling it with water.
12. **Layered Liquid Densities**: Visualize density differences by layering honey, dish soap, water, oil, and colored alcohol.
Here are the key facts extracted from the text, without opinions, numbered and in short sentences:
**Experiment 1: Colored Flowers**
1. Any white flower can be used for this experiment (e.g., carnations, daisies).
2. Cutting the stem diagonally helps the flower absorb water better.
3. Adding food coloring to the water changes the flower's color over time (observed after 2 days).
**Experiment 2: Superficial Attention (Milk & Food Coloring)**
4. Mixing dish soap with milk breaks the milk's superficial tension, creating a color explosion.
5. A cotton ball/swab with dish soap can be used to create different effects on the milk's surface.
**Experiment 3: Induced Magnetism (Magnets, Ruler, Coins)**
6. Some coins can be magnetized by placing them on a ruler with magnets underneath.
7. Not all coins are made of materials that magnets attract.
8. Magnetized coins can rotate and stay suspended when blown on with a straw.
**Experiment 4: Iron Filings and Magnets (Bottle Experiment)**
9. Iron filings are attracted to magnets when placed inside a bottle with water.
10. The filings accumulate at the thinnest part of the bottle when magnets are applied.
**Experiment 5: Piercing a Balloon without It Exploding**
11. Applying oil to the balloon's knot and opposite side (areas with less tension) allows for safe piercing.
12. Non-uniform air pressure inside the balloon makes certain areas safer for piercing.
**Experiment 6: Refraction (Glass of Water, Colored Lines)**
13. Passing colored lines through a glass of water demonstrates refraction, changing the lines' shape and creating a movement effect.
**Experiment 7: Rainbow Formation through Capillarity (Napkin, Markers, Water)**
14. Using washable markers is necessary for this experiment to work.
15. Water and ink pass through capillaries in a napkin, combining to form a rainbow.
**Experiment 8: Sharp Object through an Airtight Bag (Plastic Bag, Water, Pencil)**
16. A sharp pencil can pass through an airtight plastic bag filled with water without leaking.
17. The plastic's molecules separate and then close around the pencil, preventing water escape.
**Experiment 9: Tangerine Floatation (Tangerine with/without Peel, Water)**
18. A tangerine with its peel floats in water due to the peel's air pockets making it less dense.
19. A peeled tangerine sinks because it absorbs water, increasing its weight.
**Experiment 10: Homemade Lava Lamp (Water, Oil, Food Coloring, Effervescent Tablet)**
20. Water and oil do not mix due to intermolecular polarity.
21. Adding an effervescent tablet creates carbon dioxide bubbles, which carry dye through the oil and water.
**Experiment 11: Heat-Resistant Balloon (Balloon, Water, Candle)**
22. Inflating a balloon with water makes it resistant to heat from a candle.
23. The water absorbs heat, reducing the rubber's temperature and preventing it from bursting.
**Experiment 12: Density of Liquids (Honey, Dish Soap, Water, Oil, Alcohol)**
24. Liquids of different densities (honey, dish soap, water, oil, alcohol) can be layered without mixing.
25. Less dense liquids float on top of denser ones when poured slowly.
