OPTIONAL WORK (2º)
This is an optional work
Imagine. We play a lot of games sport which we use balls, i.e. in ping-pong I use a ball maybe with the least density of the all sports.
SO.
1)YOU HAVE TO SEARCH WHICH SPORT USES BALLS THAT IT HAS THE HIGHEST DENSITY AND YOU MUST DESCRIBE THE SPORT GAME.
2) You should write the result at the comments
UP 0.3. One week for do it. Easy!! Good luck
