I love estate sales. I usually don't like the pretenses of why they're having an estate sale, but you can find some great items for cheap. There was an estate sale not too long ago where, as I was going through the board games and other children's toys they had available, this immediately caught my eye. For only one dollar, there was no way I could let this beauty go.

Before the days of Game Boys, iPhones and other portable game systems, we had these. Interactive games that you fill with water and by pushing the buttons you would billow air into the toy creating items to float into baskets or hoops that you would try to ring into poles. They provided battery-free fun.

Once I brought it home, my daughters put down their iPad to play with this for a while, proving it's a timeless classic and items like this should still be available to the masses.
