The Water Blob is one of the first projects I shared on this blog and now that it finally feels like summer in Chicago, it’s time to share again.
It’s easy to make a water blob.
The concept is simple- you are essentially making a bag or water, or a water pillow.
We first used a painter’s tarp, but wasn’t very durable and our blob leaked a lot. I figured a large, heavy weight contractor’s trash bag would do the trick and bonus: it’s factory sealed on three sides, meaning only one small side would be prone to leaks. We used duct tape to close up about 7/8 of the open side and stuck the hose in to fill the 40 gallon bag with water. When it was filled to our satisfaction, we removed the hose and sealed the remaining opening as best we could with duct tape.
The water blob is fun to rest on, walk across, and, as you see in the video, throw things at. I’ll be honest, my boys were less concerned with watching the ripples make their way across the surface than they were simply dropping items off of our second story deck onto the blob.
And as you’ll also see in the video, sometimes I give a thumbs-up to their crazy ideas. It made for a memorable afternoon!
