Answer:

First find an elephant which has acquired an amputated human hand Next cram it and the hand into a very large lift
Elephants don't really have hands, they havefeet, I guessBut if one did have a hand, you'd just lift it the regular wayProbably using a crane, or something.
You use the shrink ray in your hidden basement and shrink it into a miniature elephantThen you hide if from your parents and you will forever live with a big secret.
Step 1 FIND your elephant with one handI cannot lift what I cannot findAs there aren't a lot of elephants around here I would need to make lots of TRUNK calls.
