When I was a kid, some 60 years ago, there were no crackers to buy but some small clay balls packed in colorful shiny foil which when smashed against a hard surface, pavement for example, they would explode because they had some substance inside. The explosion was not very strong but still a decent one and I wish I had those today, they would certainly be fun to shoot from the slingshot...

cheers,

jazz

Sure you can pack some gunpowder there -and I did it many times with devastating results-, but better skip this idea.

Jazz, someone should make some of those.

I wonder what the components are...?
I had to do a quick Google. Bang snaps etc.. are silver fulminate impregnated into coarse sand or gravel. SMALL amounts. Apparently the stuff is crazy unstable and can detonate under its own weight. Danged shame though.

I do wonder though what a primer or a black powder cap in dried clay would do. :devil:

From what I have seen on YouTube (where one can learn lots of cool stuff :headbang: ), the way to go is to make "Armstrong's mixture", inserting a small amount :hmm: inside clay balls by making a small hole, sealing the hole, and letting the clay balls dry at room temperature.

As that mixture is shock sensitive, it should produce some nice results in terms of dramatic shattering and noise.

Disclaimer: I have not tried this (yet), some might say "don't do this at home"...

Here is some relevant info on "Armstrong's mixture": https://en.wikipedia.org/wiki/Armstrong%27s_mixture

"Armstrong's mixture is a highly sensitive primary explosive. Its primary ingredients are red phosphorus and strong oxidizer, such as potassium chlorate and potassium perchlorate."

NB, NB...."Because of its sensitivity to shock, friction and flame, Armstrong's mixture is an extremely dangerous explosive. Only about 10 mg of it is used per item of consumer fireworks. Depending on composition, conditions and quantity, Armstrong's mixture can explode violently in an enclosed space".

OK... :naughty: now off to the YouTube "school":

If you are referring to the Saunders "Wing" slingshot video I made in 2017, yes, it's indeed designed for the purpose of releasing it after the shot to minimize wrist torsion effects, in order to ensure a perfectly linear launch of the projectile (well, at least in theory).

The lanyard tied around the wrist prevents the slingshot from falling to the ground.

I do not use this technique with my other, more standard slingshots.
