"A wobbling experiment kit"
Children's Science April 2019 Issue"Interesting work development site Kodomo no Kagaku Research Laboratory" is "Experimental kit for wobbling". We make three types of structures: vibration control, earthquake resistance, and base isolation using only paper.
At first glance, it is difficult to see the difference, but in reality there is a slight difference. You can experiment with how to shake the pulling seismic motion by moving or tapping it to create horizontal and vertical vibrations, and by varying the structure of the body.
This time as well, the tool to prepare has "a ball-point pen or iron brush running out of ink",Tools used to remove screen tones and instant letteringIt is also recommended to use. There are various names such as "burnisher" and "transer". (Some people call it lettering peeling or earpicking.)
The author still uses the ones I bought at an art supply store over 20 years ago (or maybe even earlier), but it seems that this is the one that is currently on sale. If you have an art store near you, it may be better to go directly and there is no shipping cost.
By the way, in the case of this transer, in the case of thin paper, the streak is made with a small ball. The spatula type on the opposite side can be used when making a package from cardboard. Make a thin slot with a width of 2 mm to 3 mm on a hard paper as thick as a paper file, cover the paper you want to make a line there, and push it from the top of the paper with the spatula side of the transer to make it concave. .. You can create beautiful ruled lines that look like products.
This time, I made the theme of "Memo", but while I was investigating the structure of the earthquake, it was very difficult to make a work to explain it, but it seems interesting, I will pay attention to the world of earthquake again when I have the opportunity. I thought there would be something.
Honya Plan, who also cooperates a bit with the final "After School Detective Maker" on the same page. I might write about that as well, so stay tuned!
