How to send a video from iPad to iPhone, no iMessage?

On my school iPad, I have a video saved into my library that I want on my phone. It's about 3 minutes long. How can I send it? Problems:
1. School took iMessage off iPads
2. Too long to send to myself through email.
How else can I send this? We have to turn them in tomorrow. This is urgent. Are there any apps that I can use to send video? Suggestions?

The easiest way to transfer the file would be to copy it directly with the USB cable. If you do not have that, an app such as Dropbox or Google Drive should work well.

You might be able to download Dropbox (make an account) to the iPad (maybe not) and have it uploaded to "the cloud" for free and then download it to your computer or iPhone with the Dropbox app.

You can use the itunes or you can also download a software.
