AI Thread Summary
Creating a rocket using common household items like Mentos and Diet Coke has a high failure rate, prompting the exploration of alternative methods. Attempts to generate thrust with hydrochloric acid and magnesium to produce pressurized hydrogen gas, as well as using Alka-Seltzer, have not been successful. Suggestions for reliable rocket designs include using dry ice for rapid gas production without flames and matchstick rockets that utilize the combustion of match heads for thrust. The discussion reflects nostalgia for simpler times when such experiments were learned through hands-on experiences rather than online resources.

I have an idea of creating a rocket using mentos and diet coke, but the failure rate is really high. I also tried reacting HCL + Mg in order to create pressurized Hydrogen Gas in the bottle, in order to make the rocket thrust upwards. I also used alka seltzer in creating a potential rocket, but to no avail.

I would really appreciate if more ideas can be posted in this thread, of creating a rocket using some of the ordinary elements in the periodic table, or using things that are available (mentos, alka seltzer, etc).

Thanks

Look up "Matchstick Rockets." They are tiny rockets that use the pressurized gases of a burning match head to generate thrust.

Dry ice is a very reliable method of producing a lot of gas quickly, if you want to keep a soda-bottle, non flame producing design.
 
Wow, this takes me back. I remember making matchstick rockets with my friends 40+ years ago when I was a kid. We didn't have YouTube videos in those days, either, and I don't remember how we figured them out.
 
Those where the times when we had no youtube, TV nor internet, but we had parents. I was shown how to make a matchstick rocket by my Dad.
 
What on Earth is a parent? Could I find it on the Google somewhere?
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
