Balloon Bust

You will need a large box, balloons and money: $1 or $5 bills. Roll your bills up and put them into the balloon. Blow a little air in and knot it. Put it in the box. Repeat for as many balloons as you'd like to send.  

I started to run out of room in the box, so I ended rolling a couple with 3 bills together.  Or you could have a bonus balloon with a $20 in it or something. They have to pop the balloons to get the money out!  The dog didn't like this one I hear. POP! POP! POP!
