Sure, it was like replicating ideas when you needed to follow black and white tutorials from old books, but now, with the many specialized YouTube channels that exist and the millions of useful and freely available videos on the Google video network. , now it is a piece of cake.

7. Create plastic from peanuts
If you want to start creating plastic figures, for example, to build the physical part of some electronic devices made from scratch, you can take advantage of the properties of peanuts dipped in nail polish remover.
8. Miniature rocket with aluminum foil
With toothpicks (toothpicks), aluminum foil, a lace, a long toothpick, a specific miniature rocket design and various match heads (matches), you can achieve a striking pocket arsenal.
9. Make instant ice
Purified bottled water and put in the freezer for 2 hours and 45 minutes, achieve striking properties in its solid state, a state to be achieved when exposed to different materials at room temperature.
