 Waterbears  live all around the world. They are commonly found around moss or lichen, so I encourage you to look for them.

 Quick tutorial on finding tardigrades:
</p>
<ol>
 <li>
  Collect some lichen or moss (I found lichen on the bark of a tree. Be careful not to damage the bark while scraping off the lichen, it houses many microorganisms and protects the tree.)
 </li>
 <li>
  <p>
   <figure aria-describedby="caption-attachment-69518" class="wp-caption aligncenter" id="attachment_69518" style="width: 225px">

 <li>
  Place the lichen in a petridish and cover with tap water. Leave the sample soaking over night. This allows the waterbear to hydrate and become active.
 </li>
 <li>
  Prepare some slides and search your sample under the foldscope! This may take a while, so have patience.
 </li>
 <li>
  I assembled a slide with one well in which I placed a chunk of lichen and a view drops of water from the petridish. I did this step 10 times, always renewing the lichen and water, until I saw my first tartigrade!
 </li>
 <li>
  I actually got really inpatient and used a big light microscope to scan my petridish and check for living organisms before I reutrned to the foldscope.
