The taste test is one of the best tests. If the water tastes at all wrong you will KNOW that something is wrong with your water. If the water is not pure and clean enough to drink then it certainly is not good enough for anything to live and breath in.
I would say yes it would be ok not to put anything at the bottom of the aquarium. Gravel, stone and plastics are usually used for appearance. If it is a freshwater aquarium and if you plan on using live plants then gravel is necessary.If it is a salt water aquarium then it is necessary to use live rock and live stone.
Garden soil is not suitable for an aquarium (tropical or cold water aquariums). The soil will pollute and cloud the water with soil particles, debris and live organisms that could cause disease to the fish. Only use special aquarium equipment and ingredients: washed gravel, etc.

No, Visine is not recommended for use in aquariums to make them clear. It is designed for eye care in humans and may have harmful effects on aquatic life and water quality. It is best to use appropriate aquarium products to maintain clear water in your aquarium.
No, because if you boil a water and put it in the aquarium the tendency is the aquarium will crack.;) SO EASY!
Provided you soak out all the salt it should be OK. The hard thing to do with drift wood is to sink it.

Add an aquarium heater. Make sure you choose a heater with the correct wattage for your aquarium's water volume.
The root word for "aquarium" is "aqua," which is Latin for water.
You can raise a sea urchin in a salt-water aquarium. There are no fresh water sea urchins so you would need a salt-water aquarium to properly care for the urchin.
