In forge buy a bunch of the big crates and stack them.

Then put a receiver teleporter on top in the center of the crate.

Then put 1 more crate on top & delete the ones under the receiver so that the crate floats.

Make sure to put the receiver on an unused channel.

If you put a 2-way teleporter on top of the floating crate and delete the crate and the receiver the 2-way never falls.

Tip: you can hide anything that will fit on the crate. I put a ghost on the rate in sand trap and my friends were wondering where got it.
