"Confetti pump"
[Children's Science, November 2021]
(https://www.seibundo-shinkosha.net/magazine/kids/66727/)'s "Fun Craft Development Site Kodomo no Kagaku Seisakusho" is "Paper Blow Pump". The paper is used to make a three-dimensional bellows structure. The folding process is quite difficult, but don't give up and try to complete it!
Do your best not to lose heart during the folding process!
This is a picture before gluing the transparent PVC board.
It is interesting to see how it flies like popcorn when you put a ball of tissue or copy paper in it in addition to confetti.
By the way. You may try to make the enlargement of the copy larger (smaller) than specified in the journal.
Oh, I see... When it's bigger (smaller), it means 00... I see...the shape here has to be that shape... I hope you will try it. I hope you will give it a try.
See you next time.
