You could make small chalks with ice cube trays, big fat toilet roll or kitchen roll chalks. Round yogurt pot chalks. Or use popsicle or plaster of paris\/play-doh molds for something different.

Tin foil or film wrap.<\/li>\n<\/ul>\n<div style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\">Next you need to pepare your molds. Kitchen rolls or toilet rolls should be cut to size if they are too long for you. Tape over one end to stop the chalk mixture running out when you fill them (we used duct tape). They also will need lining with wax paper or freezer paper to make them waterproof. Disposable molds like yogurt pots won&#8217;t need any preparation &#8211; you can always cut them away from the chalk if they get stuck. Coat any other molds (such as your baking trays or ice cube trays) with petroleum jelly so the chalk will slip out easily when dry. Or alternatively (and better in my experience &#8211; I have never got the petroleum jelly thing to work) you could line them with tin foil or film wrap.<\/div>\n<p><center style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\"><\/p>\n<table align=\"left\" bgcolor=\"#FFFFCC\" border=\"0\" cellpadding=\"5\" cellspacing=\"0\" style=\"width: 450px;\">\n<tbody>\n<tr>\n<td><span style=\"color: green;\"><span style=\"font-size: x-small;\"><b>Science tip :<\/b> <span style=\"color: black;\"><br \/>Plaster of Paris is a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Plaster\" target=\"new\">chemical<\/a> that reacts with water and heats up to pretty hot temperatures that could burn you. For this reason, do NOT allow your children to poke their fingers in the chalk mixture when mixing or pouring. You can find a science lesson plan that looks at this reaction <a href=\"http:\/\/www.juliantrubin.com\/encyclopedia\/chemistry\/gypsum_experiments.html\" target=\"new\">here<\/a>. But, so you don&#8217;t worry, Plaster of paris is non-toxic so the finished chalks are safe for the children to handle.<\/span><\/span><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><\/center><br clear=\"all\" style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" align=\"left\" alt=\"Homemade Chalk Colors\" border=\"0\" height=\"125\" hspace=\"8\" src=\"http:\/\/plannerperfect.com\/wp-content\/uploads\/2011\/10\/homemade-chalk-2.jpg\" style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\" vspace=\"8\" width=\"200\" \/><span style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\">Put 2 or 3 tablespoons of your paint into a bowl and add a cup of water. Mix, then begin adding the plaster of paris slowly, mixing as you go. You probably need to check the instructions on the packet to get a better idea of how much to use, but my packet said add until all the water was absorbed! I kept going until I ended up with a thick custard\/cake batter type mix.<\/span><\/p>\n<div style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\">Pour or spoon the mixture into your molds and leave to set. It will probably take a few hours! When set you can remove the chalks from their molds but they may need longer to dry out before you can use them (leave them overnight). <\/div>\n<p><center style=\"font-family: Georgia,&quot;Times New Roman&quot;,serif;\"><\/p>\n<table align=\"left\" bgcolor=\"#FFFFCC\" border=\"0\" cellpadding=\"5\" cellspacing=\"0\" style=\"width: 450px;\">\n<tbody>\n<tr>\n<td><span style=\"color: black;\"><span style=\"font-size: x-small;\"><b>Tip : <\/b>Don&#8217;t pour any leftover mixture down the drain &#8211; it could well block it.
