Rain Barrel question - Why can't I just dip the water out?

I set up a plastic (?) garbage can, well cleaned, under a downspout.  It's well covered.  Why can't I just dip the water out with a big ole dipper when I need it?  My veggie garden is tiny.  Thanks in advance for any advise!

Rain Water Collection Filtration System?

Also we were looking  at   using  one of  the floating   chlorine  tablet  holders  like  a   pool would  use  to   maybe   kill  any pathegons    that would  be in  it.

wall water fountain

I would like to make a fountain that about 2 ft wide and would be almost ceiling height. I saw one on a web site for over 36,0000. which I could never afford in my lifetime if I want to continue to eat. It looks like it is raining behind a glass or clear plastic wall. I have seen them with glass bead inbeded into something and then water washes over them. How would I do something like this ? Thank you Karen

I was wondering about use of some barrels that I procured. Answered

They had Polyacrylic acid (CAS# 9003-01-4) in them, which was being used as a calcium dispersant/scale inhibitor.  I was wondering with a good rinse, wash and soak if they would be ok for use in a rainwater collection system that feeds a garden.  I discovered that that specific chemical is also used in all kinda of cosmetics, and in many of different pills (Musinex as an example) as a time release agent.  I figure if I clean them good, how bad could it be if it's something that you would ingest anyway?

Where is a rainbow? Answered

As you may be aware, your reflection in a mirror appears to be behind the mirror. But, where is a rainbow? The Sun is over your shoulder, the cloud of raindrops is in front of you, but what is the apparent location of the rainbow? Is it between the observer and the water droplets, in the same location as the water droplets, or behind the water droplets (from the POV of the observer)? Or is it at some indefinably infinite location? I should know this... (a sketched-out ray diagram would be greatly appreciated)

Instructables HQ flooded!

The San Francisco Bay area is being hammered by a series of winter storms right now. There are gusts to 75 MPH and a torrent of rain. All that wind-swept rain has flooded our server room and created a foot-deep lake on the runways outside the control tower! If things aren't working right on the site, it's the rain's fault, really...This storm is actually pretty tame by East Cost standards, and I'm proud to report I got a little bit of kitesurfing in yesterday morning on the front of it before the wind and rain truly picked up. It's just that we have perfect weather 90% of the year here, so it's really the relative difference, not the absolute magnitude, that makes people talk about how bad it is.

Adding garden hose connection to downspout

Trying to think of a good way to add a garden hose connection to a downspout for directing rainwater elsewhere and or collection. There are diverters/whatnot out there but they seem to be ridiculously overpriced and some have low capture rates. And no, putting a barrel or container right under the downspout isn't really an option. Idea 1 = plug the bottom of the spout, then add a connection on the side, near the bottom Idea 2 = plug the bottom of the spout, and integrate a connection into it Idea 3 = use a flexible connector on the bottom which would go to a round shape, add a PVC cap and add a connection on the end Idea 4 = use a PVC downspout adapter to attach to a threaded cleanout, then add the connection to the plug Idea 5 = use two elbows off the bottom (U), and add a connection somewhere on either side of the bend I'm liking #4 at the moment, but I'm not sure about what exact fittings to use... One of these? http://images.lowes.com/product/converted/046224/046224250500lg.jpg

Does anyone have an underground water storage system?

I have four 55 gallon plastic sealed top drums barried in the ground. They are meant to store water from my washer and rain water. I have a 3" inlet running in line to the four barrels. On the other side I put 3/4 inch PVC to an inch from the bottom of the barrel. The PVC is meant to get used something like a straw in your soda. I have the straws in line to the water pump. The problem I am having is that the pump requires to be primed to work. How can I keep it primed? It would be great if there was a valve that closed when the barrel was near empty. That way the pump would continue to pump the water from the other barrels and never loose its prime. Any ideas here????? Again, these are sealed toped barrels. I cannot open them to put a sump pump at the bottom, not to mention, a sump pump couldn't supply the pressure needed for my sprinklers. Thank you in advance for any advice! ! !
