Inge and Magne's fab 3D rocket fires up and jets off.
NB! This experiment must be done by adults only, and with all safety regulations in place. Remember hearing protection and goggles.
You need:
• A rocket: either of paper or as we have: a two-part 3D-printed rocket
• Stand
• Parachute
• Fuse
• Gunpowder in a cardboard sleeve
• Safety goggles and gloves
Recipe:
1. Wear safety goggles and gloves
2. Place the rocket at a safe distance from buildings and people (and roofs)
3. Place the rocket on a stand to make it easier to ignite
4. Place stuffed gunpowder in a cardboard sleeve at the bottom of the rocket, with an opening for the fuse
5. Light the fuse and back off
6. The rocket takes off! When the gunpowder is almost burnt, it gives an upward pressure so that the rocket opens and the parachute unfolds. Ready for reuse! (Unless it lands on a roof)
About UiS Christmas Calendar 2021:
The Joule calendar is made by Inge Christ, head of The School Laboratory of Science at UiS, and UiS professor Magne Sydnes. For the seventh year in a row, they make a Christmas calendar with chemistry and physics experiments, popular amongst both young and old. This year there is so much energy in circulation that the Christmas calendar was renamed " The Joule calendar". Joule" is one of several units for measuring energy and is pronounced “jul” in Norwegian. With “jul” being the Norwegian word for Christmas, “joule calendar” makes up a fun pun!
This year’s calendar includes a mixture of experiments that can be done at home without the risk of blowing up the house as well as experiments that should only be performed in a lab while taking the necessary precaution.
