Science teacher Jacob Strickling exploded 400 party poppers at one go at a school in Sydney during a celebration for his alma mater's 40th anniversary.

The first half of the video shows Strickling and his son preparing the apparatus beforehand by drilling 400 holes into a long wooden plank and inserting the party poppers through them. In the second half, shot on May 29 at Covenant Christian School, Strickling can be seen setting off the party poppers as excited students cheered 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 its 40th birthday, my old school invited me to come and share some past memories at the celebration assembly. Ten years earlier (for its 30th birthday) I had a small machine to set off 30 party poppers. I wanted to make a bit more of a statement this time around and so built a piece of equipment to set off 400 party poppers.
It consisted of a plank of wood with 400 holes drilled into it. Party poppers were then pushed through and all of the strings were tied to a much longer pull cord. When the cord was pulled it set off all the party poppers! The machine took my son and I about 8 hours to build (and 10 seconds to set off!)
