I really like his way of explaining stoichiometry at the end… And such a SAFE way to use hydrogen & oxygen experiments. I’m definitely going to incorporate this into my science classes. Thanks so much!
+Emily Hart You figure out how much volume is in the pipet bulb by filling it with water then dispersing into an empty graduated cylinder. Refill it and squeeze out 1/6 the volume. Use marker to note the water level. Repeat. You can just copy for the rest of the bulbs.
Can u please tell me how I can purchase/acquire the flint apparatus that ignites the gasses? I want to have 20 kids do this experiment but I would like each of them to have their own equipment....
does anyone actually know what happens in the pipet when water is added? i'm guessing the combustion of the hydrogen and gas gases produces lots of heat which reacts with the water to create steam which escapes to produce thrust??
Shan Jiang : nope, remember, every action has an opposite and equal reaction. Gas isn't very dense, so when it goes one way, it pushes a small force the other way moving the rocket forward. Water is dense, so when it goes one way, it gives a lot more force on the rocket going the other way.

It is so disappointing that UA-cam won't promote such good videos.
This was fantastic! We did this lab, but I wasn't sure what was going on! Thank you so much for the indepth explanation!
Ur Lab helped me ALOT! I missed the chem lab yesterday so I am so grateful I found it on here. Thanx so much for posting ur lab. :)
Great demo video and explained so nicely, BRAVO
Superb demonstration. Fun, easy to understand. A great refresher video to have watched.
What is the best way to make the lighter? Is there a video or instructions?
You don't need a lighter. You can just mount a sparker onto PVC...
@@obiwankenobi8163 Can you provide more information for those of us who are not as handy?
One quick question- how did you determine where to place the marks on the pipette bulb so that it's exactly 1/6 increments?

That’s very cool. Excited to do this in class

ro ko : most hardware stores have these (barbeque lighters) however, they need to be modified (as he describes)
What is reacting and why?

Thank you! This was really helpful :)
So how many parts hydrogen and how many parts oxygen makes the rocket fly the farthest??
H2O so 2parts Hydrogen 1 Part Oxigen
FANTASTIC
... great!, now.I can make a tiny H-Bomb 😁
