Homemade spray rocket

One of the simpler rockets and effective I've seen, and I've seen quite a few ;-) It works by burning some type of aerosol, a deodorant or similar spray, the more flammable the better.

I've put it on my to-do list. But while I decide to do it I leave you with the video. Very very simple. And as soon as we do ours, we hang it up with the improvements we make ;-)

Alcohol rocket

En the youtube channel of dealcohol, we can find several experiments carried out with alcohol.

This simple alcohol rocket it has drawn my attention. In the line of very simple rockets to make such as the match rocket or the one for the tea bag. They are games that we can play with our children, always explaining to them the dangers of using fire and taking the necessary measures. Don't do it with them if you think they are going to try it when they are alone or with their friends. You know your children better than anyone else. The benefit of the activity is to generate that curiosity, that fascination, that makes them want to continue learning and experimenting.

Materials

This time we will only need

  • a plastic bottle,
  • Burning alcohol, the kind they sell in supermarkets that is tinted blue
  • a lighter

Procedure

Alcohol is poured into the bottle and we empty it. Then we put it in position and bring the lighter closer to the hole in the plug. So the remnant, the small amount of alcohol that has remained inside on the walls will ignite and push the bottle.

I leave you a couple of videos.
