Based on the title I was expecting to see “energetic materials”, which are carefully engineered variants of thermite.
For example, alternating layers of aluminium and iron oxide can be deposited in the same manner as seen in chip production by evaporating the materials in a vacuum chamber.
This allows layers tens of nanometers thin, essentially a perfect mixing and a very intimate contact between the reactants.
Some of these materials have far more bang per unit mass than conventional explosives.
Hammer faces would work (def wear goggles!!!). Hit the face of the disposable one with a mixture of hydrogen peroxide, vinegar and salt and wait an hour.

Does the second rusty ball really need to be a rusty ball since it is covered in foil?
Might improve the odds of reaction to have iron on both sides? Would the reaction also work if both balls were covered in foil?
Doubles the reaction.
Please try this at home. You all have rusty iron ball laying around, right?
It wouldn't be weird for someone in the south of France to have a rusty pétanque ball.
Now you can be hoisted not just in your own petard, but also in your own pétanque.
This clearly calls for thermite petanque.

Joining the thread to see where iron balls can be sourced.
Some vendor on AliExpress? Those Lucky Iron Fish?
This might work with old iron dumbbells (or modern iron kettle balls if left unpainted). Your gym might hate you for it though.
Cast iron pan left outside for a day or two.
I'd guess exact form wouldn't matter. Wrap a hammer in foil and beat up something rusty.
Does the ball need to be iron? Can we just take a 3d printed sphere, paint it with glue ,roll it around in a bucket of rust and then smash?
