Step 1: Mosquito/Insect Trap

Cut the top (just before the start of the cone) off a 2 liter bottle.

Invert the cone and place it inside the straight part of the bottle.

Glue the two pieces together, using a glue or silicon.

Add 1 tsp yeast and 1/2 cup sugar to some luke warm water, and pour the mixture into the bottle.
Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugar and emits the same gas, so the mosquito enters the bottle, thinking she will find food there. She cannot then get out.

You can use the same bottle design for a fly trap, but fill it with a putrid smelling liquid. For wasps, use a sugar mixture. For fish, put under water, and add a bit of cheese or bread.
I have not made 4 different designs, and the one like this does work, but has some problems. It also will collect rain water if outside. I finally realized, this needs to be inside a room with screens on the windows and screen doors. Then it would capture the mosquitoes that sneak inside when the door is open. Otherwise, it is guiding the mosquitoes to the room which is not wanted. I am testing a couple with just 2 one quarter inch holes in the sides. Which is faster to make, waterproof. Well, in a way,I am trying every combination I can find, but trying to remove the need to buy sugar. There is plenty of fruit scraps here in West Africa. Bottles are scarce in Kara, Togo because the public water system is good, and they drink soda in recycled bottles. in a really poor place, to need to buy anything would stop the use of this idea. And, it does not have immediate results you can see in 10 minutes, so a hard sale.Thanks for the help.
any fermentation with sugar will give off the CO2 needed for this to work. Fruit peels and scraps with some water will ferment and produce CO2. Soda bottles will work, in fact, we used 2l soda bottles for ours. even better if they have some old soda in there, as that adds sugar to the mix.
<p>cool</p>
<p>Another that I heard of lately cut a small hole about 75mm down from the neck about 35-40mm in diameter put some peanut butter in the bottom of the bottle and bury it standing up in the ground so the hole is just above the ground, cover just to hide the bottle but leave the hole exposed and you have just made one of the best mouse traps you can get and you don't have to touch the mice </p>
LED Lightbulb how value the resistor?
<p>LED's in a DC circuit act like resistors. If they are wired in parallel, they all &quot;see&quot; the same voltage and you want to put a resistance in series with the LED circuit to drop the voltage they &quot;see&quot; to a voltage that will light them but not burn them out. The easiest way to do this is to put a variable resistance (a volume control is a variable resistance) in the circuit and reduce the resistance until the LED's light, then measure the resistance of the variable resistor with an ohm meter.</p><p>If the LED's are identical and wired in series , each LED will drop the same voltage. Put the right number of LED's in series and they will drop the supply voltage (put the wrong number in series and they will not light (too many) or burn out (too few)).</p><p><a href="https://www.swtc.edu/Ag_Power/electrical/lecture/parallel_circuits.htm" rel="nofollow">https://www.swtc.edu/Ag_Power/electrical/lecture/p...</a></p><p><a href="http://physics.bu.edu/py106/notes/Circuits.html" rel="nofollow">http://physics.bu.edu/py106/notes/Circuits.html</a></p><p>https://www.google.com/search?q=resistance+circuits&amp;ie=utf-8&amp;oe=utf-8</p>
<p>Usually a small resistance (say 100 Ohms or so) is good enough for standard LEDs. You just want some resistance so you don't cause a short circuit.</p>
<p>I put my pet birds' seed mix and formulated food in clean dry bottles. Makes it easier to pour and handy to take when he goes to a friends house when we go out of town.</p>
<p>Great stuff here. I personally like the butter churn.<br><br>Before we extol the virtues of glass too much and long for the &quot;good old days&quot; of glass containers, let's keep a couple of things in mind.<br><br>First an foremost, &quot;business&quot; is concerned with profit, not convenience until convenience effects profit. Glass is VERY HEAVY. Shipping costs SKYROCKET with glass containers.<br><br>Second, glass BREAKS. Loss in shipping SKYROCKETS with glass containers. Methods to mitigate breakage loss INCREASE shipping costs AND WASTE.<br><br>Third, glass isn't any more 'biodegradable&quot; than plastic. Personally, as offensive as plastic containers are littered all over the countryside, BROKEN SHARDS OF GLASS ARE WORSE.<br><br>Fourth, safety. Broken glass is a serious safety issue around small children.<br><br>Fifth, cleaning glass is 1) EXPENSIVE, and 2) USES ENERGY.<br><br>I applaud wise use and reuse of plastics, but plastic is neither the satan that so many like to suggest it is, and most importantly, glass isn't the &quot;messiah&quot; that the same people want to say it WAS. Let's lose the &quot;good&quot; vs &quot;evil&quot; crap and focus on intelligent design and use.</p>
<p>I have made several of these products... hate to throw anything away that it is possible to recycle.</p><p>Saw the post on someone wanting to know how to make butter and asked what Ripened Milk was - it is whole milk that has sit out of the refrigerator overnight to sour so you can make your own butter. </p><p>TO MAKE BUTTER EASILY</p><p>Get a gallon of fresh daily milk, let it sit in the refrigerator for several hours, enough time for the cream to rise to the top. </p><p>After the cream has risen you pour the cream into your bottle or jar. (I use a wide mouth glass Mason jar only makes it easier). Leave this bottle/jar of cream out on the counter overnight ( DO NOT REFRIGERATE). The next morning you will have what is called Ripen Milk. </p><p>Shake the bottle/jar of cream vigorously for about 5 to 10 minutes. You will feel the difference in the weight and see small bits of butter on the sides of the jar. Shake it about 5 to 10 minutes more but slowly. You want the small bits of butter to gather into a clump. </p><p>When the butter has gathered spoon it out and into a small bowl. </p><p>Run about 1/4 cup of COLD water in the dish and use a fork to stir the butter (this takes the whey, bitterness, out of the butter). Pour off the water, if water is not clear then repeat this step. </p><p>Add salt or any other spices you want to your fresh made butter and start eating it. You can either waste the buttermilk by pouring it out, drink it, or use in a recipe. I make butter out of fresh milk every week just like this.</p>
<p>Bunch of nice ideas you got there. Thank you.</p><p>According to the plastics industry, their dirty little secret is that plastics marked &quot;recycleable&quot; are still manufactured from fresh plastic. Labels, glue, dirt, and mixed plastics in the recycling stream prevent bottles from being made of old plastic. So unless there is a massive need for park benches made of plastic and sawdust we are not going to see much benefit in society. </p><p>My plastics get reused, but it's only a delay before the landfill. Same for many reduce/reuse/but-not-recycled projects. Even putting them inside walls accomplishes the same thing as burying in a landfill. The walls will erode over time and trash is distributed over the face of the land which can possibly contaminate the rain to groundwater cycle. </p><p>These are not complaints toward the author, merely ideas to consider as we examine the entire life-cycle of reusing or repurposing plastic waste.</p><p>Have a great day and lemme know of any new solutions, I'm ready to listen!</p>
The wall only eventually erodes if it is made improperly or never maintained. Concrete structures last centuries. <br><br>There are many ways to take these plastics out of the waste stream, and that's what reusing is all about. Sure, we should look at recycling and better materials, but we should reuse as much as possible, first.
Does the plastic get brittle and break down over time? That would be a limiting factor in using for long term stuff like building projects.
<p>When using to build, you cover the exposed plastic with plaster. Plastic does NOT degrade if it is not exposed to UV light i.e. the sun.</p>
<p>A note about putting a perch on a bird house - many sites/builders suggest NOT putting on a perch. The bird small enough to use the opening doesn't need it, but it does give larger birds a place to cling to while raiding the nest, something they would have great difficulty doing without the perch. Some great ideas here, though!</p>
<p>Thanks for the &quot;clean-earth&quot; share (I hate litter). I use some of these with great success. Semper Fi</p><p>I too had the rain problem with the mosquito trap. Take another bottle, a couple of sizes bigger works best, leave the cap on but cut the top off down around the part that starts getting fat, (much like the part that you turn upside-down to put in side the trap). Then take 2, 3 or 4 (your choice), pop-cycle sticks, attach them (glue, screws,staples, again your choice) to the out-side of the trap, set the new bigger bottle (cap side up) onto the sticks and yaaa, you have an umbrella for your trap to stay out-side.</p>
<p>That is good idea </p>
<p>If you fill the bottles that you freeze, they will probably burst as the ice expands. I've done this, but only fill them partway in stages. Lay them on their sides so the expansion will be into the empty space in the bottle, not against the walls. Top them off 2 or 3 times and put back in the freezer.</p>
<p>They are also used as free lights in other countries where poor people live in very dark homes, by cutting a hole in the roof and inserting a bottle upside down. They become a solar tube. I always keep a plastic quart fruit jar frozen for use in coolers, and store water in them during hurricane season. I bought a Soda Stream so I don't have to buy those bottled drinks anymore! I WILL make a wasp trap and put it a distance away from my house, as I am violently allergic to their stings, and they keep me prisoner in my house in the spring when they are nest-building in my carport. I keep a can of wasp spray by the front door so I can use it any time I have to open it. The nasty things have nearly killed me twice, and fire ants came so close to it once that I had to be hospitalized overnight, under continuous respiratory assistance. </p>
<p>I use them to start my garden indoors prior to it getting warm enough to take the plant outside and replant in the garden. They work great.</p>
<p>I have filled 2 12 oz bottles with sand and use them as exercise weights. Work great! Also, fill one with sand, pebbles, or heavy kind of kitty litter and use as foot massager - put on floor, roll back and forth with balls of your feet.</p>

<p>I have seen another instructable using a 2 liter filled with water, insert into the roof of a shed or outbuilding. The sun reflects and refracts from the water, I believe OP said at about a 60 watt light. </p>
<p>Substitute with 16 or 20 oz bottles cut after taper ends so top doesn't fall through. Add 1.5 to 2 inches of mountain dew. place in sunshine and out of wind and secure base in soil. Place away from work or play area. Nothing works better to collect and kill wasps. They tire from flying then overheat and drown. Does not kill bees. Other sodas will work less effectively. Make an array of 4 or 5 bottles if wasp problem is obnoxious. Secure to board or use a remnant 5 ga pail and dirt, gypsum mix, stucco mix, etc.. to deadweight and secure traps.</p>
<p>I love your ideas !</p><p>I'm sure there billions of others that could be shared.</p><p>However the problem with plastic is it is still plastic ! One day or another it will end in a trash can and be lost in nature with a very slow decay of a 100 years ! The ice pack that has been broken and cannot be filled with water will still be there long after we died and our children reached old age (ie. March 2114 !!!&hellip;).</p><p>I'm sure that you and most others will agree that we nee an alternative, and we need it NOW !</p><p>Best wishes and thank you again for your seminal ideas !</p>
How do you Ripen Milk, and if you do not have a cow or goat. What kind of milk do you get at that store? whole milk?... <br>I am a city girl and would like to try my hand at this...but the Ripen Milk threw me for a loop. (natural born blone) lol.
Whipping Cream works well, just keep shaking the bottle, it takes some time. I prefer to use/reuse a Mason jar, makes getting the butter out much easer, or leave it in the jar in the fridge and use it as you need it.
I think if you get whipping cream (the kind that you actually have to whip) it works...I meant to try it, saw a YouTube vid on it.
I do not understand why the mosequito cannot fly out of the bottle if she flew in.
The placement of the cut part works like a Maze, the get lost. They want out so take the shortest route (Up), but the door out is down at the bottom, through the hole and then up (so they never find it)
I have watched six videos of this on YouTube.com, but you are the first to say the mosquitoes are attracted to the carbon dioxide. Thank you, Andy Graham in Kara, Togo an area with Malaria. HoboTraveler.com
they are not attracted to carbon dioxide, at least not in the specific meaning of the word attracted. <br>they guide by carbon dioxide, that's how they find us humans ,even in the darkness, they keep track of increasing amounts of carbon dioxide.
I was wondering if I could just staple all around instead of trying to glue would work?
use the cap to cut out the centers and you can make donuts and donut holes
I'm glad you added the 'thermal mass" use into this. Many people tend to overlook the amount of energy that is wasted every time they open the fridge or freezer. If you're a bachelor with one jar of mustard and one bottle of beer in your fridge: refill all of your old water bottles, and stock up the fridge. When (if) you buy groceries, just remove the necessary amount of bottles to make room. This can save a considerable amount of money/power! Thanks!
your idea is also useful during those hot summer days...can you say cold potable water...ahhh refreshing...just don't forget to refill it or remove it if you need the space..
I thought most bachelors used beer for thermal mass in the refer. Some bacheorettes as well.<br />
Ha ha... My fridge 2 years ago....
Great ideas!<br>I especially loved the &quot;brick&quot; idea.<br>What a great way to recycle!!
You live in the Philippines, don't you. I know because of the Sprite which is made in the Philippines by the Coca-cola company. Btw can you put something der to scoop up dirt?
Sprite is one of the most common drinks in america :) It is very cool.
Now that I'm smarter by 2 years, yeah I realized that about 5 months after posting my above comment. It's actually a tad more effective here because of the heat, so the contrast between the sprite's low temp and the high temp of the surrounding environment makes for a oh-so-refreshing drink B-)
Sprite is available here in North America as well. Generally soft drink are bottle in the country of consumption.
I took several 2L bottles, drilled 4-5 small holes in each of the caps, then filled the bottles with water and put the caps back on. I then took all those bottles and stuck them cap-end down in the soil around my vegetable plants. It's a cheap way to water your plants while you're on vacation!
yeah, we do the same thing, but for bee food. We stick the bottle upside down in a small hole in the roof of the bee hive. Works good.
This works so fantastic. We swear by it now. Excellent for container gardening.
Did the trap last summer and it worked well. We just left about one fourth of the orange soda in the bottle after a few days all that was left was a thick orange syrup which the wasps loved. Caught quite a few, unfortunately it was no match for the nectar my sunflowers and acorn squash were producing. Soon the dozens of wasps would chase us back in the house if we dared step out the door. Soapy water sprayed on the leaves worked pretty well, but you have to spary at night. The Idea is to wash off the nectar. There were always still a wasp or two standing gaurd and even once we sprayed there was always a handful in the day.
great ideas. instead of precious soil, how about trash, like plastic bags, used as filler? ive heard of a peace corp student who built a small school like that. She asked 20 students to bring as many bottles as they could find to the site, and she used the trash that littered the streets in the community to fill the bottles with, then some chicken wire, cement and paint, now the kids have a school.<br><br>stay classy planet Earth
what is this i don t understand
