Please post details on how to make these strobe rockets.
It's an investment, and a hobby.
Basically you've got 3 mainparts.
Stick
Motor
Header
Just like school rocketry but the header is the end effect.
In a strobe rocket, the composition incorporates the strobe effect into the motor(lift/"jet").
Chemical composition vary greatly, but the process is time-consuming, can be tedious to start, & requires special tools.
When it's streamlined, a 'rocket press' is the way to go.

Most tools are going to be aluminum & brass to avoids sparking composition.
The easiest start project would be a simple bp(black powder) rocket.
Easiest & funnest header(kaboom) would be a simple salute.
Granular black powder, 'meal-d', Sulphur, KCLO³(pitassium nitrate for whistle mix/burst charge)& KCLO⁴(potassium perchlorate for flash powder) charcoal powder, binders like bentonite clay, rice hulls, sponge titanium, & aluminum powder are just a few chemicals needed.
There are a thousand cool things to do with pyrotechnics.
The best foot-in-the-door is to join a local pyrotechnic organization (club), and explore what they offer.
On my bucket list is a trip to Malta to build beraq/maltese shells.
Here's one a club member built during the plandemic. We shoot several times a year. It's a fun hobby.
