Can I put giant timber bamboo in water glass to regrow roots from new cuttings?
You were asking about giant bamboo which is somewhat different than what I usually describe/think of when I talk about bamboo. Are you sure this is the real giant variety as it would not usually be grown in residential settings. Not all bamboo is cold hardy and only some varieties can grow up to zone 5. Here is a link that describes the giant variety:

There are different types of bamboo, but the most common type is called "running" (rhizomes) and it is invasive and a lot of thought should be given about where it will spread before you plant. The other type of bamboo is called "clumping" and it does not spread like the "running" type and can many times be planted in more areas.
Here is a link that gives a lot of information about bamboo and should be a "must" read for anyone contemplating (or even thinking about it) planting any kind of bamboo.

If you are still interested in trying your hand at growing new bamboo then here are some links that have very good, easy to follow, instructions. Just pick one and decide if you wish to study other suggestions. I just like several sites to pick from when starting something new.

You can, but bamboo is quite invasive and you may be sorry you planted it.
I believe it's better if you have the roots or the pre-roots (that turn into them)
From what I understand, you can start a new bamboo from cuttings in a glass of water. First: cut at an angle a healthy section about 10 inches long containing at least 2 nodes and 2 inter-nodes. Next: dip cut ends in wax to prevent rotting. Then: Place in water for several weeks in a sunny location until roots have begun to form.
