Picture of Hot Dog Cooker / Solar Oven
IMG_1670.JPG

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

Picture of Materials

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

Optional

Magnet, Plastic Wrap, Tape

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?

Great Instructable by the way! Thanks for sharing!

WOW that is nice!!

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.

We do recommend having the item cooking be as dry as possible by getting rid of any extra water.

Hopefully someone wiser will also answer your question.

Good luck and great oven you have there!

Thanks! Though credit goes to you for creating this Instructable!

That massive oven sounds awesome! I'll take into consideration what you said about having dryer hot dogs. Thanks!

It heats up great! I used magnets for an adjustable base.

it only got to about 130ºF but I think it can get hotter. I got it so clear by stretching it out with tape

Thanks for making and posting!!

How hot did yours get? How did you get your plastic so clear? That is how it should be. Great idea with the magnet!

Isn't the heat somewhat bad for the magnets? Just wondering.

You'd have to get them a LOT hotter to hit the Curie point of the magnet to ruin it. :)

very innovative idea

Save one of those silica gel packets (the ones that say "do not eat") 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.

we made a couple of changes.

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.

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

That sounds really cool. Could you add a picture?

Just kidding this was great!

My Q:How hot does the oven need to get to cook a hot dog

Cats Science Club (author)  JackyL7 months ago

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.

But I need a temperture for my sc project

Cats Science Club (author)  jackeline_L7 months ago

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.

and also what size of skewer do I need and also what kind of knife

Cats Science Club (author)  jackeline_L7 months ago

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.

Can you attach foil to the in side of the container with tape , and then cook flat food like cookie dough?

Cats Science Club (author)  JackyL7 months ago
I do not think it will get hot enough to bake cookies. But you could heat items at the bottom. The key is to have the cooker always facing the sun. Once the sun is off of the cooker, the cooker cools down quickly.

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.

Cats Science Club (author)  nissan07121 year ago

Do you still have the can? ;-) That would be pretty cool to see the old cans.

How does this work and why does it work?

Also how hot dose this have to be to cook?

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.
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.

Gregory Grookett thanks this is very cool I would have never thought of doing this but I think this coming summer I'm going to have to try it I'm in the winter months here in the USA.

I gregory grookett have also started following you hopefully you can do the same I am new to this site. Thanks again for the awesome post I'm going to share it sincerely your new follower gregory grookett.

I tried this and came up with another method. Instead of plastic, I cut the top and bottom off of a 2 liter bottle. Cut it along it's length, so you can re-roll it to fit inside the can. I also cut the Pringles Can opening about 1/2 inch smaller the the length of the plastic. This give it a 1/4 inch overlap on each side. I also cut the Pringles Can opening wider. A little over have the width of the can and used the two flaps as reflectors. For storage, I use two rubber bands to get the flaps closed and to secure the skewer. That way I can still have chips with my hotdogs!!

yes excellent job, if you could paint the outside black(something non-toxic I hope) - I think it would help with the heating up.

The problem with coating it with black is that black matte surfaces both absorb and emit more than shiny surfaces. As it is hotter inside the solar oven, the best thing you could do would to have a vacuum container and a shiny surface on the outside (just one would be good). This is mainly the principle of a vacuum flask :)
