Prepare the Table: Ensure that the table has a sturdy base and is at a comfortable height for visitors to place their heads inside. Sand any rough edges and paint the table in a color that matches the illusion's theme.

Create the Opening: On one side of the table, measure and mark the area where visitors will put their heads. The opening should be large enough for people to comfortably place their heads through but not too large to spoil the illusion. Cut out the opening using a saw or other suitable tools, and smooth the edges.

Lay the clear acrylic sheet over the table opening. Make sure it fits perfectly and covers the entire opening.

This is just a simple reflection of light creating this illusion.
