MacGyver Science: Royalty + Marriage + Vivaah Sanskar + Zinc + Henna
Disable a Motorcycle
Some dudes are trying to escape with a motorcycle. MacGyver uses a strap with a hook and launches at the motorcycle. The hook grabs onto the chain and then Mac pulls so that the chain pops off the gear.
Oh, sure — this would be pretty hard to accomplish, but it’s at least plausible. Normally these motorcycle chains are fairly difficult to remove, but it’s possible it was loose to begin with.
Henna Oxidation Test
So, there is a henna smudge on a murder victim. As part of the wedding festivities, many people were getting henna on their hands (henna is a type of temporary body art — it’s pretty cool). MacGyver comes up with an idea to use all the social media posts to match the henna smudge with an actual person.
When henna is applied, it interacts with the oxygen in the air (pretty much everything does this) which causes it to change color. This is an oxidation reaction. MacGyver just needs a relationship between the color of the henna and the time it takes to get to that color. Then he can find the time the henna was applied and look for someone that posted an image to identify the killer.
Instead of waiting for a long time — MacGyver builds a little oxidation oven to speed things up.
