Rubber band and hands. ^_^
You bring your hands together and position it so there is a very small outlet of air to the front when you hit your hands to the ground. The air channel you produce should make the rubber band jump forward.
The basic rule is whoever gets to the target “finish line” first.
What the rewards or punishments are depends on the players.
However, back in the 80s, a monetary value was added to the rubber bands.
The thin, rainbow coloured rubber bands are the cheapest.
Then it goes up from there.
1. Yellow
2. Green
3. Blue
4. Red
5. Orange
6. Violet
7. Gold - the highest valued rubber band. It is also the most expensive to buy. And it is thick and heavy.
You can trade, for example ( I no longer remember the actual exchange rate) 10 Greens to get a 1 Blue rubber band.
However, you will rarely find anyone trading the rainbow coloured rubber bands for anything.
Oh, the trade exchange rate has nothing to do with how much the rubber bands actually cost in Philippine Peso. Haha. I have no idea how it worked, it just is.
And that's how new rules and rewards were added.
For example, in our games (and usually where I was the challenger):
* Whoever can get 4 Reds to the “finish line” will get 1 Gold band from each player who joined.
* Whoever can get an Orange band to fly this high (more below), will get 2 Gold bands, or equivalent, from each player.
Re: fly this high. Another kid will put their legs on top of each other, and in harder challenges, we also add our arms.
And yep, it is doable.
* Another rule, who can make a {colour_here} band jump the farthest.
