Recently, I met up with a friend who is(quite understandably) interested in domino runs(however, due to resource managment we used jenga blocks), and tower building(also with jenga blocks.). So, after messing around for some time, we created three variations of the Saer-Kielstra split(thus called because of our last names). The basic principle for it is: a jenga block falls from the top of a higher area, and then at the bottom, there are 2 more domino runs set up that go in opposite directions, and both are triggered by the one block. We created three variations. The standard variation, the delayed variation*(it delays the second domino run for a few seconds), and the reverse variation(a domino run triggers another one higher up, and continues on it's way).
*was originally called the quick variation.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: The Standard Variation(called, Because It's the Basic One).
In the standard variation, place one block (with it's width pointing upwards)and make sure that it is aligned with the top flat area. Then, place another block(this time on it's front, like in the picture), 2 block widths away from the first one. It should be under the top flat area. Then place a block orientated exactly like the first on top of the block under the flat area. Place one block on top of the first block, orientated like in the picture. Then place a final block on top of the 2 blocks, in the same place and orientation as the picture. Build one domino run on the top area, so that it will fall down on the block sticking out from under the flat area, and then build 2 more, heading away like in the picture.
Step 2: The Delayed Variation(called, Because It Delays 1 Domino Run).
build 2 small domino towers either side of where you will put the main domino bit, and place one domino on top of the towers, like in the picture. There should be a higher area just behind the domino, just like in the picture. Then place a domino upright on the bottom place, making sure it is aligned with the higher domino block. Then place a domino on top of that one, and build 3 domino runs like in the picture, one falling down from on top, and 2 more heading away from the 2 domino blocks.
Step 3: The Reverse Variation(called, Because It Goes Up Instead of Down(if You Know What I Mean)).
Make sure the higher area is only a bit more then one domino high. Stack 3 dominoes on top of each other like in the picture. Make sure they are as close to the higher area as possible. Then build a domino run on top of the higher area, and build one under the higher area heading towards the 3 blocks, and another heading away from them. The domino run which will trigger this variation will be the one under the top area.
