SUGAR ROCKET MAKING

    WE'RE GONNA IGNITE IT. HI FRIENDS, WELCOME TO  TECH. TODAY WE'RE GONNA DO A ROCKET. WE'RE GONNA DO A SUGAR ROCKET. IMPORTANT NOTE IS THAT KIDS SHOULDN'T DO THIS WITHOUT PARENTS' PERMISSION. WE'RE GONNA MAKE THIS ROCKET AND FIT A CAMERA ABOVE IT. DON'T YOU WANNA KNOW HOW WE MADE ALL THESE? LET'S GO TO OUR WORKSHOP! WE'LL START OUR WORK. FIRST WE NEED SUGAR. THEN POTASSIUM NITRATE KNO3. 

THESE ARE THE MIX FOR ROCKET FUEL. WHEN WE GRIND AND MIX THESE, IT WILL BECOME ROCKET FUEL. SIMILARLY THE NEXT THING WE NEED IS CLAY. THIS IS TO SET IN ROCKET'S BODY. THESE 3 THINGS, SUGAR, POTASSIUM NITRATE AND CLAY ARE TO BE GROUND. WE'RE GONNA GRIND SUGAR FIRST. WE'RE PUTTING IT IN A MIXIE. SUGAR HAS BEEN GROUND WELL. NEXT UP, WE'LL GRIND POTASSIUM NITRATE. NEXT WE'RE GRINDING THE CLAY. WE SHOULDN'T GRIND SUGAR AND POTASSIUM NITRATE TOGETHER BECAUSE IT MIGHT END UP IN FIRE. SO SUGAR AND POTASSIUM NITRATE ARE TO BE GROUND SEPARATELY. NOW WE'LL GRIND CLAY. WE'VE GROUND THE CLAY FINELY. SO WE'VE GROUND SUGAR, POTASSIUM NITRATE AND CLAY FINELY. NEXT UP, WE'LL MAKE THE ROCKET FUEL MIX. FOR THAT, WE CAN TAKE 65% POTASSIUM NITRATE AND 35% SUGAR. THAT IS THE CORRECT RATIO TO BE TAKEN. 65% POTASSIUM NITRATE. SO WE'VE TAKEN 65G IS WHAT WE'VE TAKEN. NEXT SUGAR IS 35%. IT'S 95G, IF WE ADD 5 MORE, IT'LL BE 100. SO THE 35% SUGAR AND 65% POTASSIUM NITRATE WHICH WE WEIGHED SHOULD BE MIXED PROPERLY. THIS IS TO BOND WELL TOGETHER. SO WE'LL TRANSFER IT TO ANOTHER BOWL TO MIX. 

WE'LL CLOSE THE BOWL WITH LID AND MIX IT. SO WE'RE SHAKING IT WELL LIKE THIS. IF WE PUT A COUPLE OF MARBLE BALLS, IT WILL BE A FINE POWDER. OR YOU CAN DO LIKE THIS AS WELL. WE'LL SHOW THE POWER OF MIX NOW. WE'LL IGNITE THE SUGAR FIRST. NOTHING HAPPENED OTHER THAN MELTING. WE'LL TRY KNO3. EVEN THAT DIDN'T BURN. SEE WHEN WE IGNITE THIS MIX WHAT HAPPENS. SEE IT BURNS WELL. THIS BURNS WELL BECAUSE THE KNO3 WE ADDED IS AN OXIDIZER. IN ORDER TO GET OXYGEN TO CATCH FIRE ON SUGAR, WE ADDED THE KNO3. IF WE MIX IT IN PROPER RATIO, IT WILL IGNITE WELL. WE'LL START THE FILLING WORK OF ROCKET. FIRST WE NEED 11CM 3/4 INCH PVC. THEN WE NEED A WOOD STICK. I'VE JUST MARKED IT. CHECK THE MARKING'S SIZE. THE CONDITION IS LIKE THIS BECAUSE WE TRIED IT SEVERAL TIMES. THAT'S WHY IT IS LIKE THIS. IN THIS PVC PIPE, WE CAN ADD THE CLAY WHICH WE GROUND. IT'S BETTER TO USE A FUNNEL. OR YOU CAN MAKE A PAPER FUNNEL AS WELL. WE CAN INSERT THIS STICK INSIDE THIS UNTIL THIS MARK GOES IN, WE CAN HIT AND TIGHTEN IT. WE HAVE COMPLETED THE FIRST LAYER. NEXT WE'RE FILLING THE MIX. WE'LL ADD IT IN. ONCE WE ADDED, WE'LL INSERT THE STICK IN. JUST HIT IT WITH YOUR HANDS. THEN FILL AGAIN. ONLY IF WE DO SO, WE CAN FILL MAX AMOUNT OF FUEL.   NEXT WE'RE GONNA NEED UP TO THIS LEVEL. UNTIL THAT GOES IN, WE CAN FILL IT. NEXT, WE'LL ADD CLAY INTO IT. THE REMAINING PORTION IS TO FILL THE CLAY. SO WE'VE SET THE BOTH END OF PVC PIPES WITH CLAY AND FUEL IS IN THE MIDDLE. NOW WE'LL TAKE 5MM DRILL BIT AND INSERT A HOLE IN.

 WE'RE DOING IT MANUALLY. JUST ROTATE IT. IF WE USE DRILLER, IT MIGHT FIRE. SO, WE'VE SET THE HOLE. WE'VE INSERTED IN THIS LEVEL. WE'LL TAKE A FUSE. BEND LIKE THIS IN ORDER TO LOCK INSIDE. IF WE INSERT LIKE THIS, IT'LL BE LOCKED IN. WE CAN SLOWLY INSERT INSIDE HOLE. NOW WE'VE REACHED THE END. NEXT IS TO SET THE ROCKET ENGINE IN TO A STICK LIKE THIS. WE'RE GONNA TAPE IN THIS WITH INSULATION TAPE. WE CAN TIGHTEN IT. THE REASON WHY WE TOOK INSULATION TAPE IS EVEN IF IT GETS HOT, IT WON'T COME OFF. SO WE'VE ROLLED ONE SIDE. SIMILARLY DO ON NEXT. THIS IS OUR SUGAR ROCKET. THE WORK IS COMPLETE. WE'VE COMPLETED OUR FIRST SUGAR ROCKET. WE'VE DONE A FEW ROCKETS HERE. NOW WE'RE GONNA TEST IT. WE'RE ABOUT TO LAUNCH THE FIRST ONE. WE'LL INSERT THIS STICK INTO A TUBE HERE. THEN ONLY IT WILL BE STABLE AND GO UP STRAIGHT. WE'RE ABOUT TO IGNITE IT. SEE HOW HIGH IT GOES. WE'RE CONVERTING OUR CAMERA INTO WATER PROOF. IF WE USE CASE, IT WILL BE HEAVY. 

SO WE'RE USING A FOOD WRAP TO WRAP THIS CAMERA. WE'VE DONE ONE COATING AND IF WE CONTINUE 2 MORE TIMES, IT'LL BECOME WATERPROOF. WE'RE TYING THE WATERPROOF CAMERA INTO THE ROCKET WITH INSULATION TAPE. SO WE CAN SEE THROUGH THAT. WE'LL INSERT IT INTO THE TUBE NOW.   WE'LL IGNITE IT NOW. IT DIDN'T LIFT WELL. WE'RE DOING ANOTHER ONE. WE'VE INSERTED INTO THE TUBE NOW.       THE FUSE HAS IGNITED, THE ROCKET WILL LIFT NOW. AWESOME!   COULDN'T SEE. IT GOES TO THE ORCHARD. RUN... GO STRAIGHT.         THIS DIRECTION. THERE! OUR ROCKET'S TAIL IS MISSING. IS IT WORKING YET? NOT WORKING. NO INDICATION. WE'LL CHECK THE FOOTAGE.     WE'VE MADE A DIFFERENCE IN OUR NEXT ROCKET. WE'VE ADDED A WINGTAIL IN THIS. SO THAT IT WON'T ROTATE ACCORDING TO WIND. WE'RE FIRING UP THIS NEXT. WE'VE INSERTED INTO TUBE. WILL IGNITE IT NOW. SO THE ROCKET WITH WINGTAIL.  

 NO IDEA WHERE IT WILL FALL. RUN! OVER HERE! AWESOME! WE'VE GOT THE CAMERA. I RECKON IT IS NOT WET.   RECORDING IS OFF.   HOPE YOU ALL LIKED TODAY'S VIDEO. THIS IS THE CAMERA WE USED XIAOMI'S YI. STILL I'M AMAZED BY THIS. THE ROCKET WENT ALMOST 300FT HIGH.   EVEN AFTER FALLING FROM SUCH HEIGHT, CAMERA IS WORKING FINE. THE ONLY THING IS THE FOOTAGE OF FALL HAS NOT BEEN RECORDED IN ANYTHING. IT IS GETTING AUTOMATICALLY OFF AT THAT POINT. THIS CAMERA IS AWESOME. HOW WAS OUR ROCKET? AWESOME RIGHT? NOW IT'S DARK HERE.
