Chances are, by fun you mean teacher-not-like-the-reaction which i totally agree but the only thing I can think of for a fun reaction is layering it with elements that don't chemically combine or the simple food coloring idea. you could make a rainbow of layers!that would be fun...sort of
No reaction occurs
Chemically, it creates an exothermic reaction and can be quite dangerous.
the colour becomes brown. there is no chemical reaction
If you add acid to water, the water slowly turns into a dilute solution of acid. If you add water to acid, it creates a large amount of heat (exothermic reaction), which can be very dangerous.
you can add more H2SO4 to complete the reaction you can add water and then by filtration
No reaction occurs
water turns blue
You would add water through a hydrolysis reaction to reverse the condensation reaction (dehydration synthesis) that you started with to form the starch into a polysaccharide. All in all, you would just add WATER.

The product of nonmetal oxide water is oxyacid.
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
It's an exothermic reaction that produces calcium hydroxide.

the mixture would fizz as u are doing a neutralization reaction
When 10g of sodium are put into 100g of water, the reaction produces only 109.6g of sodium hydroxide because of the sodium's solvency. Some of the sodium is displaced in the reaction, and this is why it does not seem to add up.
