10ml of Methanol is added to dry sand. The mixture was stirred until no more bubbling occur and the sand look uniformly wet.

Does this indicate that the dry sand and methanol are reacting?

I'm guessing yes, but is this a trick question?

The bubbles are just the air comming out from between the sand grains as the methanol fills the pores.

A chemical reaction is a process that results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change, and they yield one or more products which are, in general, different from the reactants.

Do you still have sand and methanol in the end?
Where the bubbles simply air bubbles displaced from the sand?

(Silica) Sands are like Glass and, Will Not react to Methanol, your bubbling myth be air trap-ed on sand.
Try the same with watter and you will see bubbles also,
Some Acids react with impurities on dirty sands, but pure silica sands, wont react at room temperatures, with any thing I can recall.
Remember that Glass its used on laboratory equipment to work with an ample range of substances.
Methanol = Alcohol see reference below the molecular formula is CH3OH. its an Organic compound.
I suggest you make the "inverse experiment"
Take a silica recipient, ( Glass).
Fill it, with Methanol (use one made from Mexican Maguey trees), "Tequila", if there its any reaction, i`m sure it´s because you are drunk. happy experimentation my friends. yes, ....it`s a tricky compound, very tricky, you better find a designated driver to mess with it.

What is making bubbles? is it just the physical mixing or is it a product forming? physical mixing would be like when you fill a glass with water, you get some bubbles that go away after few seconds. The other type of bubbles would be a product forming after a reaction. (Think vinegar and baking soda, or if you're chemically sophisticted, HAc +H2CO3:).

mixtures dont mix chemically!!
sadly bad name!

no reaction!!

hope it helps!! :)
