Science teacher Jacob Strickling ignited 40 gas-filled balloons at a school in Sydney to celebrate his alma mater's 40th anniversary.

The video, shot on May 29 at Covenant Christian School, shows Strickling torching balloon after balloon lined up on a horizontal pole. The display culminated in the ignition of a large green balloon, not before putting on a pair of safety goggles and pulling out a retractable stick that would allow him to bring the flame to the balloon from a more guarded distance. Cheers of excitement can be heard from the students in the audience.

Strickling is known for conducting explosive experiments, some of which can be found on his educational YouTube channel, Make Science Fun.

To celebrate Jacob Strickling's old school 40th birthday he was asked to go and share some memories with the students. He was very keen to create some memories as well, so as part of the speech he ignited 40 gas filled balloons. It was a lot of fun! You should have heard the children scream when Strickling came out with the giant 40th balloon at the end.
