<What to prepare<\/span><\/h2>\n

\"\"
\nEmpty plastic bottles (circular ones containing carbonated beverages)
\nCutter
\nClay
\nGlass Rod
\nVinyl Tape
\nScissors
\nHydrogen Cylinders
\nChuckerman.<\/p>\n

<\/h3>\n

\uff1c1><\/span><\/h3>\n

Cut off the bottom of the PET bottle. Be very careful not to cut your hand with the cutter, as it is slippery.<\/span><\/p>\n

\"\"<\/p>\n

\uff1c2><\/span><\/h3>\n

Attach the clay to the glass tube and insert it into the mouth of the plastic bottle. Fill the gap tightly to prevent air from escaping.<\/span>
\n\"\"<\/p>\n

\uff1c3><\/span><\/h3>\n

Wrap vinyl tape for reinforcement.<\/span>
\n\"\"<\/p>\n

 <\/p>\n

\uff1c4><\/span><\/h3>\n

Hold the tip of the glass tube with your finger, attach the tube to the hydrogen cylinder, insert the tube at the top, and slowly fill it with hydrogen.<\/span>
\n*If you put hydrogen in the bottom first, it will mix with the air (oxygen) in the PET bottle and cause an explosion at the moment of ignition.<\/span>
\n\"\"<\/p>\n

\uff1c5><\/span><\/h3>\n

It ignites immediately after removing the finger.<\/span>
\nAt first, the flame is silently lit because of the 100% hydrogen content.<\/span>
\n(Actual hydrogen fire is colorless, but has a slight orange tinge due to soot from the gas.)<\/span>
\nAfter a while, heat is transferred into the PET bottle and mixes with the air (oxygen) from below, releasing energy all at once and creating an explosive atmosphere.<\/span>
