Your videos look cool but they are not practical if you do not show step by step paces with audio. Let us know what materials are used beyond cardboard. How does your cardboard get so hard that is can be drilled. What is that liquid? It definitely isn't flour paste. Is it resin? How long does I take to dry? If these things cannot be explained then your projects are bait n switch (fake) along the way...
Hey man... I tried to do this project and it was a real mess. You can't just create something and call it a tutorial and when put to the test it's no where near what you do. I must say that YOUR PROJECTS ARR FAKE AT SOME POINT. Cardboard and paper doesn't get so hard that it CAN BE DRILLED. If your project is real then PLEASE DO A STEP BY STEP TUTORIAL AND SHOW THE MATERIALS YOU USE. Stop just making short videos like these and also put in audio as well... After trying your project I failed miserably... Your tutorial makes no sense if it can't be done in a practical way... SO MAKE SENSE OF WHAT TOU ARE DOING AND DON'T JUST MAKE A VIDEO... PROBE THAT YOUR CRAFT IS REAL AND ITS NOT SWITCHED UP AT SOME POINT...
