This is an excellent way for kids to learn about the power of the sun. By adding water through the tubes the black tubes absorbs energy from the sun and heats up the water. We wanted a cost efficient way to demonstrate this so we used black garden tubing, scrape cardboard, some glue, and a template. The template was necessary for the age group we were work with. Add water and the sun = hot water!

Step 1: Materials

The materials you will need are

- Zip Ties

- Glue or Tape

- 3Ft Black Gardening Tube

- Sharp Pencil

- Water Dropper or Pipet

- Water

- Water Collector - We used a Pringles can lid

- Thick Cardboard

- Optional Template

<p>How much is diameter of the black garden tube ?</p>
<p>Thank you for the comments and suggestions. I believe the tube was a 1/4 inch tube.</p>
<p>Great !</p><p>Add more coils in serie, or parallel !</p>
<p>well done ! </p><p>Cover the coil with a plastic or glass plate !</p>
<p>Nice project !</p><p>As pump, you can use, a small solar fountain pump ( small pump and a small solar panel ) The solar panel is low voltage. Safety !</p>
<p>Awesome project!!! I wish I had a few teachers like you as a youngster!!</p><p>I will do this with my kids, Just showed them your instructable and they were excited to try it. </p><p>Thanks </p>
<p>We hope you do try it. Send pics and temps if you do, please.</p>
<p>What a great science project. Thank you for sharing how to make these. I kind of want to make one. :)</p>
How hot was the water?
<p>The temperatures varied from kid to kid and the amount of time allowed to sit in the tubes. We recorded results but I did not save the information and I do not want to guess. Sorry.</p>
<p>That's a nice little experiment and perfect for the age group. </p>
<p>Thank you!</p>
Good science experiment and learning for kids.
<p>Thanks! The kids did learn and wanted to learn more.</p>
