Make your own Water Blob for $15 or less!

Summer around our house is filled with mornings at the park, afternoons at the pool, evenings outside, and fresh grass beneath our toes! Our kids LOVE being outdoors, and they often find things to do with water. They love everything from water balloon fights to running through the sprinkler. My littlest guy is always trying to keep up with the big kids, so finding some things for him to do is an adventure in itself. Last summer I made a HUGE water blob for the big kids, so I decided to make a smaller one for him and then another one for the big kids. This is an easy project to do and it took me about 30 minutes from start to finish before the little kids were able to play on it.

Supplies Needed:

  • Plastic Sheeting
  • Duct Tape
    • I found penguin tape on the clearance rack at the store…the kids liked it, so I went with that since it fit into a “water theme”….right?! 🙂
  • Scissors
  • Hose & Water
  • Small towel

To begin with, fold the sheet in half and then line up along the corners. I purchased a 10′ x 25′ roll with the intention of making a blob for the older kids as well, so I cut off a 5 foot section (from the 25′ length) then folded it in half making a 5′ x 5′ section. It ended up being just the right size.

To get started, tape the corners and make sure there is a good seal. Then tear off a long strip of the duct tape and lay it underneath the bottom layer of the sheeting. Fold against itself the top layer to create the seal. Repeat this along the 3 sides, leaving a small gap at one corner for the hose to fit in.

Once you have sealed all sides, place the empty blob in the area where you want to play (Once it’s full you won’t be moving it!) and have your little helper turn on the hose for you. If you have older kids this is a great time for them to hold the hose in or push out any air bubbles in the sheeting.

When it is almost full hold the corner up and turn off the hose. Grab the towel and dry off the corner. Seal the remaining portion off with duct tape. Check for holes and leaks and repair/reseal as needed.

As the kids’ heels pull on the sheeting you may need to do some repair work. This is fairly easy to do by wiping off the area and placing a piece of duct tape on it. *I filled this water blob up quite full and would leave more room the next time I make another one so there’s not as much pressure on the plastic sheeting.*

If the blob is usable again for another day you can pull back the area where you filled it up to drain. Drape over a table, some chairs, or even a fence to dry out a bit. I emptied this one and used it again the next day when the neighbors came over to play.

The kids will love feeling the water as they lay, jump, or slide on the water blob without getting wet. This activity kept my little guy busy all afternoon! Altogether I spent $15 for all of the supplies ($10 for the 10′ x 25′ plastic sheeting, $4.50 for duct tape), but this smaller portion of the total supplies for the water blob came out to about $5.

***PLEASE make sure you supervise young children and make it a rule to not lay face down as it can lead to suffocation.***

    What an awesome idea!! I would totally love to do this with my nanny kids this summer. They will be just finishing 2nd and 4th grade. How much weight do you think this water blob could withstand?
