Ukrainians are making Molotov cocktails by the thousands.
Typically you need to get close and put your own life at risk to be effective.
Why not use of surgical tubing, exercise bands etc. to build DIY sling shots to launch these from a greater distance? Perhaps instructions on building air cannons (potato cannon) with large PVC pipe and starter fluid, butane lighter fluid etc or hair spray as fuel? Find bottles that are right diameter.
As a side note Ohio governor ordered the removal of all Russian vodka from state liquor stores...let’s send those bottles to Ukraine so the can rain down fire with Russia’s own bottles!
