This was my job for my blue sky project .Can I make a glider go 25ft with a launcher?

I thought my blue sky project went very well I completed my task of making a glider go 25ft I was very good at conversing with the people who came to my table they seemed very interested in my project. I thought James would steel the whole show with his trebuchet.
In making my glider and launcher I learned how to make a glider and scale things x2 also that simple is better. As a fun fact I learned that an aeroplane’s wing need to be able to touch each other even jumbo jets wings have to be able to touch. All in all I thought everything was a success.
