White Water Version 1.0, this a dissolved oxygen water hack that I’m trying.
Safety first - the power supply must be DC voltage as in DIRECT CURRENT ONLY. The reason for this caution is we are using water and electricity. Um, hopefully by now kiddies you know water and electricity don’t play nice together. So I repeat DC as in DIRECT CURRENT ONLY for your low voltage power supply. Next I’m not responsible for your actions but also please consider don’t try this if you have children or pets that could roam into your grow space. PUT THUS UP ON A HIGH SHELF OUT OF REACH OR USE A BUCKET LID..... Now the disclaimers are invoked - moving forward.
The materials are simple
2 pieces of metal, stainless or alloys may work better here
Non conductive spacers as in wood or rubber
DC low voltage power supply. *** read the label jag-off *** don’t make assumptions if you can’t see the label clearly. This one has an output of 12 volts dc.

I’m testing this with 1/4 inch hardware cloth fencing but could be done with stainless steel or this funky new lightweight metal called alu-min-ium don’t fret but it rhymes with condominium.....
Next the 2 pieces of metal should be very close to each other but not touch or make contact - hence the spacers. I’ve used wood shish-kabob skewers, you could use air hose tubing or most any clean non metallic and non conductive material.
Power supply yes once again DIRECT CURRENT ONLY
Power supply low voltage DC or DIRECT CURRENT POWER SUPPLY ONLY
I made 2 concentric rings about 4 inches in diameter for the first one about 4 & 1/2 on second one.
this pic is to illustrate the gap or spacing so the two pieces of metal don’t touch each other. Note the spacers help to hold the gap.
Wire from low voltage DC power supply attached to outer ring
Wire from low voltage DC power supply attached to inner ring
Bucket of water
drop the device in water first then plug into outlet - in a moment tiny bubbles begin to rise
after 5 minutes the top of water is white with tiny bubbles. I’m wondering what the results will be with different or more clean metals like aluminum or stainless steel also note the paint paddle bit on table. I paddle stir my water with a battery drill anyway but wanted to try this hack. After 15 minutes the bubbles appear to be in top 1/2 inch of water but wonder if left for an hour or overnight if the bubbles will be suspended all the way to the bottom of the container. Who knows? Also curious about the effect of wetting agents like yucca or surfactants like non scented dish soap.
one last time DC DIRECT CURRENT POWER SUPPLY ONLY
update to add: preliminary results after 1 hour tell me that the bubbles remain in the top 1/2 of the water.... now to try different metals, wetting agents and surfactants.
