I also made this neat water wall but we haven't tried it out yet. I found it on pinterest. It cost $20.00 to make but only because I couldn't get to any garage sales. $17.00 for the sheet of peg board which I cut down (and the other part goes into service in the garage.) The tubing I salvaged from work it was unused and they were going to throw it out so I re-purposed it. The funnels were from the dollar store $2.00. I could've easily found these at a garage sale but couldn't wait. The water tub will be one of the many totes we have around the house.
I also made a bubble station so the kids can refill for themselves. I can't wait to take these activities camping this summer. It is so cheap to mix up our own bubble solution and we already have a ton of wands and cups.
I posted the bubble solution recipe already this week.
