you can use Mentos and baking soda
If you add vinegar to baking soda it fizzes (that's what they use for some bottle rockets).
carbon dioxide doesn't dissolve easily in water. so you have to use presure to make it a solution - as soon as you release the pressure by opening the bottle, the carbon dioxide bubbles up.
Mixing baking soda with vinegar creates a chemical reaction that releases carbon dioxide gas, causing the mixture to fizz and bubble. This can create a "quick explosion" effect, which can be fun and entertaining as a science experiment. However, it is important to follow safety precautions and not use this reaction in a dangerous or inappropriate manner.
What happens is a chemical reaction. Vinagar - acetic acid Baking soda - sodium bicarbonate you are producing sodium acetate with water if you keep adding more vinegar on the baking soda (search "hot ice" on google) note that vinager is not pure but only 5 percent acetic acid the rest is water. for the best fizz use 1200 grams of vineager and 84 grams of NaHCO2 (baking soda) this is one mole of each obviously you can change the proportions. The reason this makes a perfect reaction is because that makes one C2H4O2 molecule react with every NaHCO2 molecule. The bi-products are CO2 H2O and NaC2H2O2
When I drank the Pepsi I felt it fizz in my mouth.
To make a volcano project, you can use materials such as a plastic bottle, baking soda, vinegar, food coloring, and perhaps some clay or paper mache to create the volcano structure. The reaction between the baking soda and vinegar will create a bubbly "eruption" when combined in the volcano model.
You can make flat drinks fizzy again by adding fresh carbonated water or soda to the drink. Alternatively, you can use a home carbonation system like a soda maker to add bubbles back into the drink. Swirling the drink gently can also help restore some fizz.
For a good long time if it is kept properly stored. Here is a test you can use to make sure your baking powder is usable . Put water in a teaspoon and sprinkle a little bit of the baking powder in the water. If your baking powder is good the water will fizz sort of like a soda does. if you don't hear or see the fizz then baking powder is no good and should be tossed out.
The reaction between baking soda and vinegar generates carbon dioxide gas. It can be used in chemical volcanoes and other science projects.
i say you use baking soda i use it every time i make cookies
If your talking about food i would use flour to make things thicker not baking powder and definitely not baking soda...you use that to make CRACK...
We can use baking soda if you wan to make slime
