It could be a baloon or giant beach ball or excersize ball, saran wrap then tape, then you cut it in half or only as far apart as you have to, get it apart and tape it back together. Or in Allens case stick a baby in there and tape it back up. Who just happened to have an egg and a baby at a moments notice.
To get that level of transparency you need a slightly different technique. If you use saran wrap all the wrinkles will block the view, so I did not use saran wrap on this one. Instead I put the tape on backwards (sticky side out). The second layer covers up the stickiness and then you have two sides that are not sticky.
There is no "like" button here. So I'll have to say something like OOOOOOH!
