Explosions in Slow Motion

13 crazy experiments-explosions you shouldn't do at home.
Starting with the propane-C3H8 filled balloon explosions. Slow motion reveals that initially there is blue flame which takes quickly yellow color. Secondly, acetylene-C2H2 (prepared by adding calcium carbide to water) flame is black due to unburned carbon particles. Nitrocellulose-C6H7O2(ONO2)3 burning is fast, but small pieces can be safely ignited on palm due to low density of nitrated cotton.
Trimethylborate-B(OCH3)3 exploded with green flame.
Rubidium-Rb and potassium-K reacted explosively with water.
Then came methanol-CH3OH cannon.
Aluminium-Al and lead tetroxide-Pb3O4 or simply aluminothermic mixture was ignited with a chemical time fuse.
Bomb group was neutralizing solvents that may have had some unstable peroxides formed. They used plastic explosive (contains hexogen-C3H6N6O6, also known as RDX) and a detonating cord. The second explosion was picric acid-C6H3N3O7 and some plastic explosive.
The last was a mixture of potassium permanganate-KMnO4 and aluminium-Al.

Killzone Intercept

Killzone Intercept occurs during the events of Killzone 3 as the ISA evacuate Helghan. A small scout squad is called upon to stall a large group of approaching Helghasts that plan to cut off the ISA convoy from reaching the extraction point. Outnumbered, the squad takes on the task with hopes of getting everyone off the planet alive.

Director's note:

"This is another film project that was 2yrs in the making and only possible with unbelievable amounts of work and support from friends and family. It amazes me what can happen when a group of talented people are passionate about a project. On previous projects, we have never had any form of support from the actual game creators. Luckily, Guerrilla Games was kind enough to give feedback and recognition for a fan film project fueled by our love for the games. Other developers should take notes. Now, enjoy the film!"

GI Joe Vs. Ski Fun Ken Doll

GI Joe accepts a kamakazi downhill challenge from Ken Doll for pink slips. Originally created for a snowboard film, it was shelved for fear of copyright issues. Oscar Goldman, Mr T, Luke Skywalker, Horshak, Vinny and others from Welcome Back Kotter, Evil Knevil an even Ponch from Chips all have doll apperances in this classic tale of too much alcohol paired with too little testosterone.


Dynamics of Unconfined Spherical Flames

Using the soap bubble technique, we visualize the dynamics of unconfined hydrogen-air flames using high speed schlieren video. We show that for sufficiently weak mixtures, i.e., low flame speeds, buoyancy effects become important.
