I decided to include in the review this paper toy that has a mechanism that works with elastic string and pops when you take out of the envelope. I have to make some changes because the some flaps are breaking (or I need a stronger glue).
Well meanwhile I miss going to the ''Lucha libre'' because I am really stressed of having to do a presentation of my works on my sesame street japanese and I want to yel to somebody. Wish me good luck, at least if they do not enjoy my works they will laugh at my pronunciation.
