is there anything useful that can be done with soda cans? i've seen a couple of art projects but I wanted to do something more useful.
There is! So there's a couple of different things that can help your farm but I'm going to explain how to make aluminum pop cans into roof tiles. This requires a few tools, but I found it to be simple. If you don't have the tools right now, you can always prepare the cans as shown in the first step, and then use them all when you get the tools needed.
Circular Saw, or Router, or Saw with Dado Blade
Drill and bits
Uncrushed aluminum cans
2 pieces of 1x6 hardwood board
Two 1-foot 5/16" metal square rods
Step one: Gather cans
A 24 inch x 24 inch area will use from 36 to 50 cans depending on the vertical spacing and shingle style, which means you'll need 900-1250 cans for a 10 foot by 10 foot area. Remember to rinse your cans before storing them to prevent bugs, or better yet, prepare your cans as they're produced so that you don't get overwhelmed by the amount of work needed, and to save space.
Step two: Cut them into little sheets of metal
This gets sharp, so wearing gloves is important. Use tin snips (I found scissors dulled too quickly) to cut the top off the can at the seam where the can bends. Cut down the center to the bottom and then cut off the bottom of the can. You now have a rectangular piece of aluminum sheet metal.
Step Three: Cut your wood into a template
Use a pencil and square to mark the 1x6 board to the measurements in the picture. This should be a hardwood so it holds up to the abuse. Using a circular saw cut the receiving die (negative?) grooves as shown above. You are cutting it so it looks like the grey, and the white will be the next step.
Step 3: Attach Square Rods to the Template
Drill holes in each end of the two 5/16" square rods and screw them to the upper board so they are lined up with the channels on the negative die . These rods come in 1' lengths at a local hardware store.
Step 4: Clean and Add Hinge
Clean up the grooves with a chisel and hammer if needed.
Add a small hinge or just staple a can (see picture) as a hinge to keep the die halves lined up.
Step 5: Insert Pre-Cut Aluminum and Smash It
Insert aluminum and release the power of the beast. There are two types of shingles made here by placing them in one or the other can slots on the die. The shingle with the two ribs will give the strongest cover by providing two layers of aluminum in the overlap. The shingle with the two ribs and a lip will cover more area but gives only one layer of aluminum.
Step 6: Start Your Roof With the Drip Edge
Once you have a few small bundles of shingles, take them, your tin snips, some extra unpressed aluminum rectangles and a staple gun to the roof. Loosely fold the aluminum rectangles in half and staple them overlapping on the bottom and side edges of the roof. On the side edges, make a small 90 bend for the shingles to hook onto; see the picture. Make sure the overlap is correct on the side drip edges.
Step 7: Attach Shingles
If you were doing this on a big roof where you had to walk around, avoid stepping on the shingles by working from one end of the roof up to the caps and then across. When attaching, staple the shingles about 1/3 of the way down from the top; you'll need two staples per shingle. I highlighted the yellow square where a mistake was made. These staples should be under the fold, not exposed. This had to be redone after the pictures were taken.
Step 8: Cap the Top
Fold a lip lengthwise on some more aluminum rectangles so they have a round exposed edge and staple + overlap them across the ridge. The last cap piece will need caulking on the staples unless you try some tricky folding.
So there you have it. How to make durable roofing shingles using only aluminum cans. Here's a video of the tiles being made, but not how to make the tools.
Plants love starch, so if u have cooked pasta or boiled potatoes save the water, let it cool and give it to ur plants. DO NOT GIVE THEM BOILING WATER THEY WILL DIE, I REPEAT THEY WILL DIE. I add a bowl under the pot with the holes (I forgot the name of it but you know what i mean). Then I put it in the refrigerator to cool and water my plants with it once its cold.
Plants loves coffee grounds. My friend gave her aloe plant coffee grounds and it grew like crazy.
Eggshells are a natural fertilizer. Wash out the slimy stuff from the eggshell and then ground it up into a fine powder, you'll know its ready when it look like fresh crack you can snort (please dont snort the eggshells). You can use a food processor if that helps. Sprinkle the powder on the soil.
Banana peels are a natural fertilizer too. Sun dry the banana peel, you can cut it up into smaller pieces for it to dry quicker. Its ready when its looks like bethany's heat damaged hair: crunchy. When the peels are crunchy, crush it up into a powder. Sprinkle the powder on your soil.
Talk to your plants. It actually helps them grow. Talk to them bout random shit, my plants are literally my therapist.
As you can see in the picture bellow, that my exercise book is quite damaged, due to it's bad quality and not because I used it too much.
Since I have already written important notes in it, and it still has many empty pages left I didn't wanted to just trow it out, buy a new one and then copy the notes into the new one.
So instead I have mended it (even if it's such a shame that a not even cheap notebook became damaged in such a short time, because of the thin materials.)
For the mending I used a thick and strong thread and a sturdy needle.
Unfortunately my sewing still doesn't solve the problem of the thin cover paper. And the idea of strengthening the material with a duct tape or another layer of glued thick paper only came to my mind when i have already finished it.
To sum up, with this mending I have prevented the cover from further tearing up. So I can use the notebook for this semester too, which is a relief for me because my notes will be in one book. Furthermore I don't have to throw out otherwise empty notebook.
This spherical refrigerator is buried underground, keeping food cool without using electricity.
Groundfridge is based on traditional root cellars – spaces dug into the earth to preserve food and drink. It is designed to be buried underground where, due to thermal inertia, temperatures are constant throughout the year.
According to Weltevree, burying the fridge allows it to remain consistently between 10 and 12 degrees celsius throughout the year, meaning it can be used to store produce such as vegetables, wine, or cheese.
The company claims the storage capacity is comparable to that of 20 standard refrigerators, meaning it can hold up to 500 kilograms of food.
Constructed from lightweight laminated polyester, the Groundfridge is resistant to intrusion from roots of nearby trees or plants.
