This game involves setting up small trampolines to allow a ball bearing or marble to bounce along a number of them in succession, hitting the target at the end, or ending up inside a can placed there. Based on the action game of years ago, Bing Bang Boing, this pastime will keep you both busy and entertained. 
Step 1
Obtain at least 4 peanut/nut cans and empty the nuts into another container. Either paint the cans or glue construction paper on the outside to give them a finished look.
Step 2
Cut eight quality balloons between the neck and the widest diameter, as indicated by the line in this photo.
Step 3
Stretch each balloon taut over the top of each can, with no slack. Do not make it overly tight or the balloon will snap off.
Step 4
Construct a 12" (30.5 cm) long ramp from 1/4" (.63 cm) square dowels, with a 3/4" (1.9 cm) brace near each end. The ramp segments used for spacers are 1/4" (.63 cm) apart and made from the scrap pieces of the dowel.
Step 5
Use two 7-1/2" (19.5 cm) pieces, a 7" (17.8 cm) and 1-1/2" (3.8 cm) piece, as shown in the image, for the support of the ramp.
Step 6
Rest the ramp on the support.
Step 7
Put the ramp and support structure on top of a stack of books. Tape the support and the bottom of the ramp to the books to keep it steady.
Step 8
Set up the cans where you think the ball will fall once it rolls off the ramp or bounces off the previous trampoline. Set books under some of the trampolines so that the bearing can be made to go in a circular or zigzag path. Place an empty can or an unsuspecting action figure to be knocked over after the last trampoline. 
Step 9
Launch your ball bearings or marbles and enjoy!
Tips
- Instead of making a wooden ramp, another option would be to use a hard bound book with a wide groove by the spine. The book to be used as a ramp is held at an angle by other books placed under one end.
- Still another option is plastic or wooden corner molding - the type you'd find at a hardware supplies store.
- To make it easier to tape down the bottom of the ramp, make the brace for that end 1-1/2" (3.8 cm) long, or just glue a piece that size next to the existing one if necessary.
- Try releasing multiple balls very close together, but not touching, or they will collide at the first trampoline.
- You could also replace the peanut cans with plastic drinking cups.
Warnings
- Remove the balloons from the cans when they aren't being used, or else they will weaken and tear.
