What should I get Papa?

Hi everyone,
sorry I have not been posting very much. I am wondering what to get Papa for his birthday. Please email me suggestions (no clothes please, Mama already got him a lot of those).I want to get him something which he can use for a long time and which he really will use.

As many of you know, I am signed up for an online program called Center for Talented Youth by John Hopkins University. I became eligible by getting a good score on an exam right before I fell sick.

Every week, I have assignments, both physical and digital, which are due at the end of the week. Week 5 was so hectic, I had to take a week's extension on three projects! I still need to turn in two of those three by tonight, as tonight is the end of week 6. Thankfully, all my week 6 projects are done. Yesterday, I made a paper airplane, and it flew 59.16 feet!! That is the most out of all my classmates I think! I also made a balloon powered paper plane, which ran on a track of fishing line which was threaded through a straw taped to the plane. It traveled 498 cms on it's longest flight. There are many other projects like these, except that some are much harder and some are just PDF files which I have to fill in and email to my instructor. It is a very interesting course, and I am learning many new things every day.
