Re: [Origami] Where do you press the traditional frog to make it jump?

2014-12-30 Thread Jorge E. Jaramillo
I asked about where the traditional frog had to be pressed for it to jump
properly and several people answered. Thanks for that.

By watching the recommended videos I noticed that it indeed had to be
pressed where the diagrams tell you to. My problem was that the paper was
too thick and pressing on that spot wasn't easy and I had to coarse the
paper to bend, but once it was released, it made a much bigger jump than
when pressing where I was doing it.

I think depending on the age of the kid playing with the model you could
teach him/her where to press.

Jorge E. Jaramillo asked how to make a traditional frog jump.

At minute 3:48 of this video http://youtu.be/rc9lVHvfzMY you see how to
press the back of an Origami frog to make it jump.

The model in the video is my preferred jumping frog with the exception,
that I do the first few steps a little different. The differences are minor
though. First I fold the horizontal middle line, then fold both sides to
the just made line. Then I make two waterbomb bases at both ends of the now
rectangular paper without creasing the middle line between them. The
remaining part is identical. The thinner and stiffer the paper that you use
is, the better it will jump. I usually fold it from 9x9cm of a very heavy
paper and it jumps a good 3 meters at ease.

That is also one of my favorites, together with the business card frog 
(in one of its many variations) as that is the best use I've found of mine.
Maybe press the back should be interpreted as press the back end. 
What do our English speaking friends say?

Anyway, I agree with Tavin's demonstration and Jorge's statement.
I usually explain to press or flick quickly down at the back edge or end 
of the frog.

See my old photo-sequence of the jumping frog:

pressing the lower step makes it work fine
I'm sure I have to press the upper step, that is the behind-most edge 
of the back, not the lower edge as in nearest to the ground, as 
illustrated in my photo. But maybe I just misunderstand the reference 
made here.


Happy jumping,
Hans
