A few weeks ago I saw this idea for water blobs floating around online and decided to try it ourselves the next time we were having friends over to play. Then I decided to share with you guys how to make a water blob which is a great water activity for kids (and adults) in the summer.
Can I just say that this “water blob” was amazing amounts of fun. I layed on it, the kids jumped on it, slid across it and spent the entire day doing all sorts of crazy acrobatics. We loved it so much that I almost can’t wait to do another one. And the next one will have glitter in it… tons of glitter.
So what is a “water blob” and how do you make one? Simple. A water blog is a large piece of plastic sheeting (a clear thin tarp) that is folded in half with the three open sides taped shut and then filled with water. When it is done it makes a cool dry play surface. It’s the perfect activity for hot summer days for all ages, especially the toddler years since it is safe, however my older girls played with it for hours. Later in the day we did turn on a sprinkler on top of the blob which then made it like a fluffy slip and slide.
How do you make one? All you need is one big roll of plastic sheeting and duct tape. (If you want to know how to use an iron to seal the edges of the Water Blob instead of duct tape, check out this tutorial.)
Fold the plastic sheeting in half and tape the three open sides with duct tape (it helps to have assistance) but leave open a small hole for the water hose. I also added some bright blue food coloring just for that wow factor. Next time we’re going to add glitter but you could also add confetti or small gummy items like worms or fish for a theme party. Just make sure the items are very soft with no pointy edges.
Put the water hose in it and let it fill. (The chair was holding the hose for me). When it’s totally full, tape the small opening shut and let the kids loose.
It is that simple and that fun.
- It did get a few small leaks on the edges throughout the day but we simply fixed them by applying more tape to the leaky spot. It was super simply.
- The blue food dye will fade the longer the blob sits in the sun. By 2pm our blue food coloring was totally gone but the kids didn’t care and it was a great way to teach them about the power of the sun.
- Finally around 2pm the top got a very small hole that the kids picked at until they had a small puddle to play in. I could have fixed it with tape but it was time to get cleaned up and finish our play time so I just let them play with it until most of the water had drained. It held up really well.
- This would be a great idea for a toddler aged party.
- For homeschoolers, this provides a great study on waves and motion.
So go conquer the blob! and let me know how it goes!
Edited to Add: You MUST use heavy plastic sheeting. This is not a plastic drop cloth, it is thicker, usually 4mm thick. A drop cloth is 1-2 mm thick and will puncture in minutes. Also it will roll if not on a very flat surface.
