In this Instructable I will show the readers what happens with the vinegar and baking soda reaction and what I am trying to get is what amount and form is best for an awesome reaction.

I will try:

Frozen vinegar room temperature baking soda,
cold baking soda room temperature vinegar,
1 tsp vinegar 1/2 tsp baking soda,
1 tsp baking soda 1/2 tsp vinegar,
put the baking soda down first,

Any way, lets go to step two!

Step 1: The Explanation of What Will Happen

This is what happens when the two substances mix:

The experiment baking soda and vinegar is deceptively simple: what appears to be one reaction is actually two, happening in quick succession. This reaction is an example of a multi-step reaction.

What actually happens is this: the acetic acid (that's what makes vinegar sour) reacts with sodium bicarbonate (a compound that's in baking soda) to form carbonic acid. It's really a double replacement reaction. Carbonic acid is unstable, and it immediately falls apart into carbon dioxide and water (it's a decomposition reaction). The bubbles you see from the reaction come from the carbon dioxide escaping the solution that is left. Carbon dioxide is heavier than air, so, it flows almost like water when it overflows the container. It is a gas that you exhale (though in small amounts), because it is a product of the reactions that keep your body going.

What's left is a dilute solution of sodium acetate in water.

Basing my opinion on these facts I think that the "put the baking soda down first," will work best.

Step 2: Cold Baking Soda Room Temperature Vinegar Result #1

I put some baking soda in the freezer for 20 minutes and then put it in a glass of room temperature vinegar and the result was not what I expected.

It reacted well at first and then it fizzled out very quickly leaving a whole lump of baking soda and a pool of vinegar beside it, I stirred it up and it reacted like the first time and did the same thing again I stirred it up again and nothing happened.

I rate this method:

Fizz:4/10

Duration:5/10

excitement:2/10

overall:6/10

Step 3: 1 Tsp Vinegar 1/2 Tsp Baking Soda #2

In this method I had 1 tsp vinegar and 1/2 tsp baking soda.

The reaction was small but it lasted longer than expected, still not much fizz because of the small amount.

I rate this method:
Fizz:5/10

Duration:7/10

excitement:4/10

overall:5/10

Step 4: 1/2 Tsp Vinegar and 1 Tsp Baking Soda #3

In this method I used 1/2 tsp vinegar and 1 tsp baking soda

The fizz did not last long and most of the baking soda remained dry due to the large amount, in the end I added more vinegar (so not to waste the soda) and the fizz was a bit better (not pictured)

I rate this method:
Fizz:3/10

Duration:2/10

excitement:2/10

overall:4/10

Step 5: Baking Soda Down First #4

For this method I put the baking soda down first and slightly compacted it and then added the vinegar and the result was amazing!

The solution fizzled over the top of the glass and onto the cupboard!

More fizz than expected but it didn't last long.

I rate this method:
Fizz:8/10

Duration:4/10

excitement:7/10

overall:8/10

Step 6: Frozen Vinegar and Room Temperature Baking Soda #5

This time I froze the vinegar for about 40 minutes and then added the baking soda, At first it did nothing and then once the ice started melting the fun began!

It was by far the longest reaction and it had a fairly good fizz, it went in a series of bursts as the ice melted and lasted longer than 3 minutes it was amazing!

If I had to show someone the reaction between the two elements I would choose this method by far.

I rate this method:
Fizz:6/10

Duration:10/10

excitement:8/10

overall:9.5/10
