Every morning I have to prepare my bag for a long day: classes, job, gym… That means I need a big bag to hold all kind of things. I love my sports bag, I bought it after arriving in London.
But my cool bag became more and more heavy as I keep my stuff: my laptop,
my English-Spanish dictionary,
my sport clothes,
my class books…
Yeah, it’s hard to carry so many things at once! I wish my bag were like Mary Poppins’. I couldn’t explain how it would work, but everybody would want to have one.
In a further step, it would be more usefull Doraemon’s pocket. Doraemon is able to take any magic artifact out of his magic pocket.
From the point of view of a historian, you could use it as a kind of vortex or time machine to get ancient times objects and solve old misteries now, like the Antikythera mechanism or the Baghdad battery.
