How to Draw a Test Tube
Draw a test tube in 11 easy steps, about 8 minutes. Free, with a printable worksheet.
Each picture adds one red line. Draw that line, then scroll to the next picture. Rub out any dashed helper lines at the end. First up: the tube.
Step 1: The tube
Start near the top. Draw a long straight tube down, round a U bottom, and back up to the top.
Tip Keep both sides straight up and down, the same distance apart.
Step 2: The rim
Start at the top left. Draw a little rim that steps out, across and back in to the top right.
Step 3: A happy face
Low in the tube, draw 2 big round eyes with black dots. Under them, draw a U smile.
Step 4: The liquid line
Halfway down the tube, start on the left side. Draw a flat line across to the right side.
Tip Keep it flat, like water in a glass.
Step 5: Bubbles inside
Just under the liquid line, draw 3 small round bubbles, above the eyes.
Step 6: Rosy cheeks
At each end of the smile, lightly draw a small oval for a cheek.
Step 7: Bubbles escaping
Above the rim, draw 3 bubbles rising out of the tube, getting smaller as they go up.
Step 8: A shine
Start just under the rim, inside the left side. Draw a short line down, stopping well above the liquid.
Step 9: Pale glass
Colour the empty glass above the liquid very light blue, right up to the rim.
Step 10: Pink cheeks
Colour the cheeks pink, then rub out their light pencil lines.
Step 11: Green liquid
Colour the liquid green around the pink cheeks. Leave the eyes and bubbles white. Your test tube is done!
Your finished drawing
Follow the steps above and this is where you end up: a test tube, drawn by you.
