Globo Solar


Este es un gan proyecto, una especie de globo aeroestático, solo que no se encesitará ningún material caro, ni ninguna fuente de calor. Se construirá un enorme globo con bolsas negras, esto producirá que con el sol aumente mucho la temperatura del aire que hay en su interior, y se expanda, siendo así  menos denso que el aire de afuera y permitiendo al globo elevarse  por el cielo. Desde luego que tardarán mucho tiempo en hacerlo, ya que no es tan sencillo, y hay que hacerlo cuidadosamente, para no romper las bolsas, etc.


  • 25 bolsas de basura negras (de consorcio)
  • Cinta de enmascarar
  • Un vasito de yougurt
  • Hilo resistente (como el de pescar)
  • Piedritas (estas van dentro del vasito de yogurt en caso de no transportar una camara
    y sirven como lastre.
  • Ventilador (para inflarlo mas rapido)
  • Un dia soleado, ya que sin el sol, será imposible que vuele.


1. Corta en linea horizontal a la soldadura de cada bolsa, mas o menos, a 2 CM de la soldadura.

2. Cortalas verticalmente, por la linea de doblez vertical. Te va a quedar un plastico gigante.

3. Hace lo mismo con cada bolsa.

4. Luego, arma una plancha de 5×5 plasticos y pegalos con cinta de enmascarar, unos con otros. Te va a quedar un plastico enorme.

4. Luego uni los 4 lados con cinta. Te va a quedar un Tetraedro.

5. Corta una de las puntas de tetraedro, que es donde entrara el aire (es mejor si reforzas esa boca con cinta)

6. Si el globo debe ser recuperado, no olvides agregarle el hilo.
De esa boca, podemos colgar la camara, el lastre o el GPS.

7. Inflado y lanzamiento

8. Pone un ventilador en la boca del globo (esto ya al aire libre) e inflalo totalmente, que quede lo mas inflado posible.

9. Deja el globo inflado reposar, mientras el sol, calienta el aire. A medida que el aire se caliente, el globo ira levantando vuelvo lentamente.

Aca, te muestro un video, donde se explica mas en detalle y te muestra unos vuelos.
