On my church’s 125th Anniversary, we opened the cornerstone, which had been sealed 50 years before. After viewing the artifacts within, we sealed it up again with a second container from our era. One of the things we put in was an iPad with many photos and movies of congregational activities, as well as photographs of all the pages in the scrapbooks dating back over a hundred years. We also put in the power supply for the iPad, so that future generations could power it up. This should work unless future generations don’t have 110v AC available.
