The diameter of bowl is 13 cm and the diameter of straw is 1.3 cm, respectively. You could cover the opening of bowl with honeycomb if you had at least 10 straws diameter. It becomes hexagonal if you spread all over same size circles without gaps. If the number of circles on the line passing between a vertex and the vertex of the diagonal is odd number, we obtain regular hexagon. Now we need eleven straws. If you put the number of circles on diagonal as n, we obtain the total number of straw with calculating as following formula. <\/p>\n<p><img src='https:\/\/s0.wp.com\/latex.php?latex=%5Cdisplaystyle+N+%3D+%5Cleft%5C%7Bn-1+%2B+%5Cfrac%7Bn+%2B+1%7D%7B2%7D%5Cright%5C%7D%5Ctimes+%5Cfrac%7Bn+-+1%7D%7B2%7D+%2B+n+%3D+%5Cfrac%7B3n%5E2+%2B+1%7D%7B4%7D&#038;bg=T&#038;fg=000000&#038;s=0' alt='\\displaystyle N = \\left\\{n-1 + \\frac{n + 1}{2}\\right\\}\\times \\frac{n - 1}{2} + n = \\frac{3n^2 + 1}{4}' title='\\displaystyle N = \\left\\{n-1 + \\frac{n + 1}{2}\\right\\}\\times \\frac{n - 1}{2} + n = \\frac{3n^2 + 1}{4}' class='latex' \/><\/p>\n<h4>2. Cut straws with same length<\/h4>\n<p>Measure the length with a ruler and cut the required number of straws. I&#8217;d like to make honeycomb with 2 cm and 4 cm thick. It may become uneven, you don&#8217;t have to care. The average length of them should be 2 cm and 4 cm from the law of great numbers. <\/p>\n<h4>3. Adhere straws<\/h4>\n<p>Adhere straws as below. It might be appropriate to set straws with required number before you adhere. <\/p>\n<p><a href=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/straw.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/straw-300x225.jpg\" alt=\"straw\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-4641\" srcset=\"https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/straw-300x225.jpg 300w, https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/straw.jpg 640w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><\/a><\/p>\n<p>Adhere them from bottom to top with quickly. <\/p>\n<p><a href=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/adhesion.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/adhesion-300x225.jpg\" alt=\"adhesion\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-4639\" srcset=\"https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/adhesion-300x225.jpg 300w, https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/adhesion.jpg 640w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><\/a><\/p>\n<p>Now you get honeycomb.

Wrap cardboard around the honeycomb<\/h4>\n<p>When you wrap cardboard around the honeycomb, you would have to pay attention in feature of cardboard. Cardboard has 4 mm thickness, and when you fold cardboard without incision, the folding would be distorted. It is required to bundle straws. You should put a cut inside of folding. I have purchased cardboard with 60 cm long side and 45 cm short side. To make a regular hexagonal column of 6 cm height and 8 cm side, cut out a rectangle about 6 cm and 45 cm. <\/p>\n<p><a href=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/Cardboard.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/Cardboard-300x225.jpg\" alt=\"Cardboard\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-4743\" srcset=\"https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/Cardboard-300x225.jpg 300w, https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/Cardboard.jpg 640w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><\/a><\/p>\n<p>You should make incision with fold along honeycomb as following picture. <\/p>\n<p><a href=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/CutCardboard.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/CutCardboard-225x300.jpg\" alt=\"CutCardboard\" width=\"225\" height=\"300\" class=\"alignnone size-medium wp-image-4744\" srcset=\"https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/CutCardboard-225x300.jpg 225w, https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/CutCardboard.jpg 480w\" sizes=\"auto, (max-width: 225px) 85vw, 225px\" \/><\/a><\/p>\n<p>After making incision, adhere straw to cardboard with adhesive as following picture. <\/p>\n<p><a href=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/FinishHoenycombGrid.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/FinishHoenycombGrid-300x225.jpg\" alt=\"FinishHoenycombGrid\" width=\"300\" height=\"225\" class=\"alignnone size-medium wp-image-4745\" srcset=\"https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/FinishHoenycombGrid-300x225.jpg 300w, https:\/\/www.fujiitoshiki.com\/improvesociety\/wp-content\/uploads\/FinishHoenycombGrid.jpg 640w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><\/a><\/p>\n<div style=\"display: inline-block;
