It normally behaves like a liquid or jelly, but if you squeeze it in your hand, it will seem like a solid.Experiment Materials: cornstarch, water, food coloring (optional) 07 of 20 Make Rubber Eggs and Chicken Bones Using Household Ingredients Vinegar leaches out the calcium in chicken bones, so they become soft and bend rather than break. Brian Hagiwara / Getty Images Turn a raw egg in its shell into a soft and rubbery egg. If you're daring you even bounce these eggs as balls. The same principle can be used to make rubber chicken bones.Experiment Materials: egg or chicken bones, vinegar 08 of 20 Make Water Fireworks in a Glass from Water and Dye Food coloring water 'fireworks' are a fun and safe science project for kids. Thegoodly / Getty Images Don't worry - there is no explosion or danger involved in this project! The 'fireworks' take place in a glass of water. You can learn about diffusion and liquids.Experiment Materials: water, oil, food coloring 09 of 20 Magic Colored Milk Experiment Using Kitchen Chemicals If you add a drop of detergent to milk and food coloring, the dye will form a swirl of colors. Trish Gant / Getty Images Nothing happens if you add food coloring to milk, but it only takes one simple ingredient to turn the milk into a swirling color wheel.Experiment Materials: milk, dishwashing liquid, food coloring 10 of 20 Make Ice Cream in a Plastic Bag in the Kitchen You don't need an ice cream maker to make this tasty treat. Just use a plastic bag, salt, and ice to freeze the recipe. Nicholas Eveleigh / Getty Images You can learn how freezing point depression works while making a tasty treat. You don't need an ice cream maker to make this ice cream, just some ice.Experiment Materials: milk, cream, sugar, vanilla, ice, salt, baggies 11 of 20 Let Kids Make Glue from Milk You can make non-toxic glue from common kitchen ingredients. Difydave / Getty Images Do you need glue for a project, but just can't seem to find any? You can use kitchen ingredients to make your own.Experiment Materials: milk, baking soda, vinegar, water 12 of 20 Show Kids How To Make a Mentos Candy and Soda Fountain This is an easy project. You'll get all wet, but as long as you use diet cola you won't get sticky. Just drop a roll of mentos all at once into a 2-liter bottle of diet cola. Anne Helmenstine Explore the science of bubbles and pressure using Mentos candies and a bottle of soda. As the candies dissolve in soda, the tiny pits formed on their surface allow carbon dioxide bubbles to grow. The process occurs quickly, producing a sudden burst of foam from the narrow neck of the bottle.Experiment Materials: Mentos candies, soda 13 of 20 Make Hot Ice Using Vinegar and Baking Soda You can supercool hot ice or sodium acetate so that it will remain a liquid below its melting point. You can trigger crystallization on command, forming sculptures as the liquid solidifies. The reaction is exothermic so heat is generated by the hot ice. Getty Images You can make 'hot ice' or sodium acetate at home using baking soda and vinegar and then cause it to instantly crystallize from a liquid in 'ice'. The reaction generates heat, so the ice is hot. It happens so quickly, you can form crystal towers as you pour the liquid into a dish. Note: The classic chemical volcano also produces sodium acetate, but there is too much water present for the hot ice to solidify!Experiment Materials: vinegar, baking soda 14 of 20 Fun Pepper and Water Science Experiment All you need is water, pepper, and a drop of detergent to perform the pepper trick. Anne Helmenstine Pepper floats on water. If you dip your finger into a water and pepper, nothing much happens. You can dip your finger into a common kitchen chemical first and get a dramatic result.Experiment Materials: pepper, water, dishwashing liquid 15 of 20 Cloud in a Bottle Science Experiment Make a cloud in a bottle using a flexible plastic bottle. Squeeze the bottle to change the pressure and form a cloud of water vapor. Ian Sanderson / Getty Images Capture your own cloud in a plastic bottle.
