a question that you ask your self. For example:what explodes higher baking soda, vinegar,and water or baking soda,vinegar,and orange juice or baking soda,vinegar,and root beer?
For a baking soda volcano science project, white vinegar is commonly used. Its acetic acid reacts with the baking soda (sodium bicarbonate) to produce carbon dioxide gas, creating a bubbling eruption effect. While other types of vinegar, like apple cider vinegar, can also work, white vinegar is preferred for its strong reaction and clear appearance.

To create a volcano project for a school science fair, you can use materials like baking soda, vinegar, and clay to build a model volcano. Construct the volcano shape using the clay, create a cavity for the baking soda and vinegar reaction to simulate an eruption. Add food coloring for a more realistic effect. Document the process and results for your presentation at the science fair.
Well it means when your all finished what happened. For example i did why baking soda and vinegar reacted, and did everything but results , i said well the baking soda reacted to the vinegar and then made bubbles and fizzed out of the cup sincerely, cheyann
A hypothesis is your best educated guess on what the outcome of the science fair project is going to be. So you would first need to come up with the science experiment that you want to do before you can come up with your hypothesis. Example: if your science project was mixing baking soda and vinegar together to see what type of reaction you will get, your hypothesis is your guess on what is going to happen when you mix the baking soda and vinegar together. So my hypothesis for that experiment of mixing baking soda and vinegar together is that it will foam up and overflow from the container that I mixed them in. If that happens then my hypothesis was correct. So you need to have an experiment in mind before you can make your hypothesis for the experiment.
The best science fair project is the one with a volcano. Build a volcano out of PlayDoh or clay and then use vinegar and baking soda to make it erupt.
Baking soda and vinegar is the standard way of making a papier-mache "volcano" for a child's science project. The reaction between baking soda and vinegar is immediate and can be quite intense. Too much baking soda and too much vinegar can make the "lava" erupt to the ceiling of the classroom!
One easy experimental design for a science fair project is to make a volcano. To create a semblance to lava use baking soda and vinegar. This will spew out of the top of the volcano.

Vinegar and baking powder volcano. It's always a great surprise for the kids. http://chemistry.about.com/cs/howtos/ht/buildavolcano.htm
I would firstly make a volcano leaving a hole at the top and center, then fill the hole with baking soda, then add vinegar to make it erupt.
