Water Balloon Hack

Just in time for the summer! I bought a used container of water balloons at the Goodwill the other day and I could not find the filling nozzle for nothing, so I found out that you can totally hack the process by using one of these:

 Yep, right out of your dish detergent bottle.

It might be a little soapy at first but it totally works! While doing research for this post, I found out that there are a million gadgets out there to fill a bunch of balloons at once, to self tie, etc, etc. I'm the person who is going to tie everything with my hand and when I get tired, the game ends. This way we'll have a lot of balloons for the rest of the summer.
