Innovative programs

hippos & submarines

Thinking Outside the Box

Here is an example of the way the Elgin Military Museum brings innovative thinking to education programming and makes learning fun. Expect the unexpected from us!

The following was an April Fool's Day press release that takes the opportunity to draw unexpected comparisons - albeit with a little tongue in cheek! All the while, it outlines some of the potential on offer in our education programming.

Elgin Military Museum Considers Purchase of a Hippopotamus

Executive Director Ian Raven announced today that the Elgin Military Museum is considering the purchase of a Hippopotamus. Raven was quick to quash expressions of doubt by stating, "This great beast has many similarities with Oberon class submarines such as our own HMCS OJIBWA, indeed Hippos are related to whales and dolphins. A hippo would also make a fine companion for the two kangaroos we already own and the close proximity of the Jumbo the Elephant monument only adds to the interest for the visitor."

Quick Comparison

submarine versus a hippopotamus
Smell
  • One is very good at smelling and the other smells - especially after a long operation.
agility
  • Both are more agile than they appear = hippos can run up to 30 mph and would be neck and neck with a submarine in a race.
Riders
  • Both often carry riders - hippos carry birds; subs, carry special forces - aka spies.
breathing
  • Hippos can hold their breath for five minutes or longer when submerged. Humans only wish they could hold their breath for five minutes when encountering a cold war submariner just returned from a mission.
Dung flinging
  • Hippos fling their dung / submariner dung can be flung about if the submarine has a sudden increase in pressure due to a quick dive.

Under Review

While the matter is still under review, Raven said that the synergies with the museum education program helping to illustrate how humans, animals, amphibians and machines can function in the underwater world were well worth taking the discussion to the next stage.

Submarines & Hippos - More

Now you have the hang of it, here are more:

  • Hippos also have a set of built-in goggles: a clear membrane covers their eyes for protection while still allowing them to see when underwater. Submarines have periscopes to see and induction masts to bring air into the boat.

  • With their eyes, ears, and nostrils on the top of the head, hippos can hear, see, and breathe while most of their body is underwater.

  • They both have excellent 'hearing' /sonar
Picture
  • Should not take either one for granted

  • Hippos have unique skin that needs to be kept wet for a good part of the day. Staying out of the water for too long can lead to dehydration, so hippos try to stay in the water during the day and we all know what happens to metal when it is out of the water (rust)

  • Hippopotami seem to communicate verbally and they may use echolocation similar to how sonar is used on a submarine. Even more interesting, is a hippo's ability to communicate above and below the water simultaneously by holding their head partially above the water when they send out a cry; hippos above and under water will respond.  Unlike most of the sonar on the submarine, the hippo has only one 'transmitter' (mouth) and two receivers (ears).
