Challenge to Change. La macchina per ologrammi. Costruirli in classe

Cesare Benedetti

Cesare Benedetti, SamantaAi??Parise e Serena Zanotti, hanno presentato questa esperienza al Challenge to Change di Milano, venezia, Pescara e Napoli. Fantastica esperienza presentata al Challenge to Change.Ai??Grazie a una piramide trasparente e a un iPad, siamo riuscitiAi??a creare ologrammi all’interno della struttura, come si vede nell’immagine sopra.


Che cosa occorre per costruire un ologramma

  • un foglio di materiale plastico, basta un millimetro di spessore;
  • un foglio di carta, matita, riga o squadra;
  • un cartoncino nero;
  • un taglierino;
  • uno scotch trasparente;
  • un iPad.

ologrammaAi??ologramma

Con i materiali che abbiamo indicato si costruisce la piramide da collocare sopra l’iPad. Questa piramide costituita da un trapezio ricavato tagliando delle forme di plastica sottile. I lati sono tenuti insieme da scotch collocato all’interno della struttura e sopra un coperchio di cartoncino contribuisce a tenere unito il tutto.

Notate che il vertice della piramide A? tagliato perchAi?? la piramide deve rimanere in piedi, capovolta, sull’iPad.

L’iPad proietta un film riprodotto quattro volte (alto, basso, destra, sinistra), in modo simmetrico. Collocando la piramide al centro vedremo l’effetto ologramma!
