Want this question answered?
Because people put in baking soda, vinegar and red food coloring in the volcano. The baking soda and vinegar makes it explode
nothing
the conclusion is how the volcano erpts faster after putting the baking soda , and vinegar into the volcano
It will if there is excess baking soda.
Homemade volcanoes are made from vinegar and baking soda. It "erupts" because as the vinegar and baking soda come into contact with each other, a chemical reaction takes place which causes it to fizz.
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.
vinegar and baking soda
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.
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.
Because the vinegar (an acid) reacts with the baking soda (a base) when mixed.
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!
Making a volcano for a 6th grade project is very simple. Make the volcano out of paper mache and use baking soda and vinegar for the explosion.
Vinegar and baking powder volcano. It's always a great surprise for the kids. http://chemistry.about.com/cs/howtos/ht/buildavolcano.htm
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?
baking soda and vinegar put the baking soda in first
If you are referring to your science project "fizzy volcano" then you will need a volcano structure made from cardboard, some vinegar or citric acid, some sodium bicarbonate (baking soda) and some food colouring, probably red. Just put the vinegar in a cup inside the volcano, and then add some food colouring. When you are ready for your volcano to fizz and erupt just put in a tablespoon of baking soda and step back.
