u have to take only 9.u push the first ball just a square and after u go up in the next
"room" there u take the first infotron or whatever it is and then with the ball from the
left u try to smash that thing in the middle and u take all of them.

when you arrive in the next room you smash that thing with the infotron there and you will
have 9 infotrons....

I've discovered that if you drop the infotron to the electron it will give you 9 infotrons
which completes your required infotron collection. Just push the zonk once at the
beginning because you need to pass that way again to go back to exit.
