It’s sustainability week: Aukje’s group is building a giant tred-mill, which works on walking power. Tobias’ group is building a draft station that generates power when doors and windows are opened. Lieke’s group, however, still haven’t got any ideas. Mr. Twister thinks there should be a charger for people, too. Lieke is enthusiastic. Headphones play relaxing music, there’s a sleeping mask for your eyes and a pillow for your head. Lieke is appointed volunteer to test the charger and immediately falls asleep.
