This Hot Dog Cooker / Solar Oven is simple and easy to make. We have had it reach temperatures over 170 degrees Fahrenheit on a cloudless 80 degree day. Today is a pretty cloudy low 80s day and the oven still was over 115 degrees.

Step 1: Materials


  1. Pringles can or other cylindrical container.
  2. Sharp knife, make sure you can handle a sharp object or ask for help. Kids - ask a responsible adult for help.
  3. Straight edge, we used a cut piece of aluminum laying around but a ruler would be good.
  4. Sharpie marker or other marking pen.
  5. Skewer
  6. Hot Glue
  7. Drill / Drill Bit


Magnet, Plastic Wrap, Tape

<p>Hey, this is a little bit late, but over the summer, I made the cooker. I had a few problems with the sun not staying out long enough, as well as some condensation building up... Is there a way to prevent that?</p><p> Great Instructable by the way! Thanks for sharing!</p>
I've found that if I do some hard, unpleasant work outdoors, the sun seems to stay out a lot longer.
<p>usually condensation is from temperature difference and ability for the moisture to stick on the surface. you can &quot;coat&quot; it with something temporarily to prevent sticking similar to swimming goggles, and/or use a dual pane glass/poly-carbonate window instead of shrink wrap...</p>
<p>line the can with foil with the shiny side up and that will give u <br>better heat the inside of the Pringles can is kiinda dull and put a few <br>holes in the plastic wrap so that the condensation has a way to escape</p>
WOW that is nice!!<br><br>As far as the condensation building up, we have not found a solution for that. We have built a huge solar oven that could hold a pot or 50 plus hotdogs. Not like this one but with large rectangular boxes. The plastic was always covered with condensation.<br><br>We do recommend having the item cooking be as dry as possible by getting rid of any extra water.<br><br>Hopefully someone wiser will also answer your question.<br><br>Good luck and great oven you have there!
<p>Thanks! Though credit goes to you for creating this Instructable!</p><p>That massive oven sounds awesome! I'll take into consideration what you said about having dryer hot dogs. Thanks!</p>
<p>It heats up great! I used magnets for an adjustable base.</p>
<p>it only got to about 130&ordm;F but I think it can get hotter. I got it so clear by stretching it out with tape</p>
<p>Thanks for making and posting!!</p><p>How hot did yours get? How did you get your plastic so clear? That is how it should be. Great idea with the magnet!</p>
<p>Isn't the heat somewhat bad for the magnets? Just wondering.</p>
<p>You'd have to get them a LOT hotter to hit the Curie point of the magnet to ruin it. :)</p>
<p>My dad wint cime back</p>
<p>Wait, wouldn't the plastic wrap melt, therefor poisoning the hot dog when it drips onto it? Just wondering, I'm no science expert, so if anyone could help me out that would be great. :)</p>
<p> How about we spray the outdide of the can with a lil black paint. Might help absorb more of the suns rays and help heat it up more.</p>
<p>this is amazing like me at fabiant_levif</p>
<p>you don't want condensation to form, do what the big household oven manufacturers do, put a few holes in it. Being that heat rises put the holes on the bottom. Not a lot, try a few first and work with it to see how many holes work best. Also, putting aluminum foil in it works even better because the foil helps to generate the heat. If you were to use a small mirror facing the sun directed at the foil inside the can you will see it will get pas hot as 300 degrees Fahrenheit or more. I did this as a science project when I was a kid and it worked well. I was able to cook eggs, hot dogs and even warm things in it. </p>
<p>Sweet! It makes sense on how it works. Imagine even in a zombie apocalypse you can still have a hot dog cooked. In a pinch it's great but if I had too, I'd take large reflective surface materials and build a oven of sorts.</p>
<p>line the can with foil with the shiny side up and that will give u better heat the inside of the Pringles can is kiinda dull and put a few holes in the plastic wrap so that the condensation has a way to escape </p>
<p>I am wondering how long it would take to cook? i am doing a marshmollow challenge by making a solar cooker and seeing who can melt it the fastest... how long did you guys take to cook the hotdog? </p>
There are a lot of variables. Outside temperature, angle of the sun, etc. When in Florida, on vacation, in 80 degrees it took a lot less time then in Ohio at 85 degrees F. While on vacation the family made these. Kids from 5 to 17. The older kids were able to build them a bit better and were conscience about moving them out of the shade. All the kids could do it but the opening and angles were different along with the little kids not turning the cooker toward the sun lol.<br><br>The hot dogs ranged in cook times from 30 min to 2 hours. Pretty sure the 2 hour ones were done but when the little kids would check on the ovens the sun had moved and the dogs were in the shade. The 15, 16, and 17 year-old ate theirs and said they were warm just less then 30 min.<br><br>Just last week, Fat Cat took his fourth grade class outside to cook in their pizza box solar ovens and almost all the boxes were over 140 degrees F. Outside temp in Ohio was 55 and sunny. One student actually had a marshmallow turning a golden brown. Less then 20 min.<br><br>Good luck and let us know what your findings are.
<p>hey Brilliant Cats ! Great Instructable with simple things . Best out of Waste . Thanks for &quot; insprirational &quot; sharing . </p>
Will an arizona iced tea can work?
<p>nice to see that my idea in Boy Scouts bout 25 years ago is still out there. I made this same thing back in Boy Scouts for a project. haha. nice. I didnt take pics back then though. Too bad i didnt. </p>
Nothing under the sun, Horatio!
<p>Do you still have the can? ;-) That would be pretty cool to see the old cans.</p>
<p>How does this work and why does it work?</p><p>Also how hot dose this have to be to cook? </p>
i seriously wish i did. back then i never thought of videoing or taking pics of everything i made or came up with. not like today when 9 out of 10 people are bloggers for food, cars, gardening, etc. hahaha. <br>i still believe i came up with the donut hamburger first. i created mine in 1984. the official one came out in like 2004. the LUTHER BURGER. cause it was made for luther vandross at a baseball stadium. and BATTLESHOTS. battleship with shot glasses. i made my first game back in HS in wood shop. still got the original ships somewhere.
<p>Save one of those silica gel packets (the ones that say &quot;do not eat&quot;) from opening some electronic gadget, one small enough to clip to the inside of the lid. That may cut down on some of the condensation, by drying out the air inside a little.</p>
&quot;Do not eat&quot; for a reason maybe? How about a small cheesecloth bag with rice in it?
<p>Very well done! Just make sure your tape is not 'seen' by the foil. Nobody likes tape flavored food or the chemicals that may come from overheating the tape with the sun reflecting from the foil unto the tape.</p>
<p>here we go. Hope you can see them well enough. Thanks for the inspiration.</p>
Very Cleaver! Thanks for sharing!!
<p>we made a couple of changes.</p><p>1. Used a tennis ball can for the window . Cut the ends off and then cut a long wise. Fit like a cuff. Hot glued it to the Pringles can.</p><p>2. Instead of a legs/stand . Used a shoe box with notches cut on each side on the top of the sides . The stick fit perfect to suspend the cooker and I could change the angle of the window with ease</p>
That sounds really cool. Could you add a picture?
<p>10/10 would eat the pringles again. </p><p>Just kidding this was great! </p>
<p>Got it to 115 F on a 70 F day in less than 10 minutes!!! Thank you so much!!</p>
<p>Awesome! </p><p>Pretty easy huh?</p>
<p>Yes! very easy. Thanks again.</p>
<p>This is awesome!!!!! Great Instructable! Thanks!!!!!</p>
<p>Brilliant idea, can you cook other things in it?</p>
<p>PLEASE ANSWER ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1</p><p>My Q:How hot does the oven need to get to cook a hot dog</p>
<p>Hot dogs can be eaten raw. There is no set temperature they have to get to to eat safely. I hope that answers your question.</p>
<p>But I need a temperture for my sc project</p>
<p>Unless you live near the equator or the southern hemisphere, getting high temperatures in the oven is going to be difficult at this time of the year.</p>
<p>and also what size of skewer do I need and also what kind of knife</p>
<p>An utility knife works well or a x-acto knife. Skewers were just a bit longer then the Pringles can. Measure the can you will be using and go from there.</p>
<p>I put a 1 insted of a !</p>
