Safe­ty pre­cau­tions

Warn­ing! Only un­der adult su­per­vi­sion.


  • glass mug;
  • or­ange and black gouache,; *paint­brush;
  • met­al wire;
  • alu­minum foil;
  • pen­cil;
  • scis­sors;
  • thread.

Step-by-step in­struc­tions

Coat a glass mug with or­ange paint. Add black eyes and a sin­is­ter smile, and in­sert a can­dle. Draw an out­line of a bat on some alu­minum foil, cut it out, poke a hole in it, and pass a thread through the hole. Make a wire stand arch­ing over the mug and hang the bat on it. Light the can­dle – the bat takes flight!

Process de­scrip­tion

The can­dle heats the sur­round­ing air, mak­ing it less dense. The hot air then ris­es, cre­at­ing so-called con­vec­tion flows. These flows are strong enough to make the light­weight bat flut­ter.
