What's needed is a sense of Congress, a resolution, declaring that the Justices should take a day to read The Constitution of the United States. They will conduct no other business save for reading the document, beginning to end, and studying it as if they'd not seen it, previously (because some give just that sense). And it should not simply be sent over by messenger, or the like. There should be a public ceremony. The leader of the House and Senate, together, should walk up the steps of the Supreme Court, cameras rolling, dignitaries lining the route, resolution in hand, and then hand it personally to one of the Justices - I wonder if Justice Thomas would not also consider it a good thing and appear for that purpose (I don't know)? Speeches could be made. It would be a ceremony of state, and for the purpose of reminding the Court, notably its liberal members, that Our Founders did in fact go through the trouble of crafting The Constitution, which has served this nation well for over two centuries, making this the longest lasting republican government, perhaps in world history (I don't know). I think it needs to be done.
The Supreme Court couldn't deliver a warm pizza.
I like your idea. I could see the protestors lining the way to the steps of the SCOTUS, waving the flag of the US, and having a few members of congress deliver the Constitution back to the USSC.
I can see banners and signs clearly stating the same thing...
