Straight from the archives of the eccentric (and fictitious) designer Lord Robert of Brockenhurst, this eye-catching contraption is a marvel of cardboard engineering, with no glue, tape, or other adhesives necessary! Simply pop out all the pieces along the perforated lines, fold as indicated, insert the color-coded tabs into the matching slots, and voilà: a Magnificent Marble Machine that needs only the turn of your hand to power its amazing abilities: a seemingly endless stream of marbles rolls out of the top, down the ramps, and into a funnel at the bottom. Includes four old-fashioned glass marbles. Best suited for ages 8 and up, not suitable for kids under 36 months.
