Felt-tip marker mode
Let's draw a retro lava lamp
Treat this as one playful practice round: sketch the idea loosely, simplify the shapes, then commit with confident marker outlines and bright fills.

01
Stack the lamp shapes
Draw a pale center axis, flared base trapezoid, curved glass chamber, and tapered cap, then reserve four large wax routes, two small bubbles, one long glass highlight, two short metal highlights, and one shallow shadow.
Marker tip: Ghost the chamber sides from the cap to the base before touching down. Mark all six wax positions while the lines are light so the blobs can vary without crowding the glass.

02
Shape the retro silhouette
Wrap the guides with the complete flared base, curved glass chamber, tapered cap, and the top and bottom glass rims while preserving every internal reserve.
Marker tip: Rotate the page for the long chamber curves and compare both sides against the center axis. Keep the base wider than the cap so the lamp feels planted instead of top-heavy.
-
03
Float the lava shapes
Add exactly four large irregular wax blobs and two small wax bubbles inside the established chamber while preserving the long glass highlight and two short metal highlights.
Marker tip: Mix kidney, peanut, and rounded blob shapes, but keep a clear paper channel around each one. Count four large forms and two small circles before reaching for black marker.

04
Ink the lamp and lava
Thicken every established outside edge, rim, wax shape, highlight boundary, and shadow edge, then add three short seam accents to the base with imperfect black felt-tip lines.
Marker tip: Pull the marker toward yourself along each long curve and let the line weight vary slightly. Pause at every rim so the metal and glass boundaries stay crisp instead of becoming one heavy band.

05
Pour in the retro color
Fill the established cap and base indigo, four large wax blobs coral orange, two small bubbles magenta, glass pale aqua, and shadow warm gray while preserving the three white highlight gaps.
Marker tip: Color around the wax instead of across it, following the chamber curve with visible strokes. Let the pale aqua dry before reinforcing the black blob edges so the colors do not muddy.

06
Glow up the lava lamp
Strengthen selected keeper outlines and clarify the established lamp, four large blobs, two bubbles, rims, three seam accents, marker fills, paper highlights, and shallow shadow.
Marker tip: Count four large wax blobs, two small bubbles, and three highlight gaps, then stop. A face, logo, cord, switch, table scene, sticker edge, or badge frame would turn this focused lamp study into a different lesson.
